Product Description

ACTIVE-POWER INDUSTRIES Trailer Bearing China Distributors 51256/81134 Thrust Angular Contact Ball Bearings 234432

Product Description

Thrust ball bearings are designed to withstand thrust loads during high-speed operation and consist of washer-shaped rings with raceway grooves for ball rolling. Because the ferrule is cushion-shaped, thrust ball bearings are divided into 2 types: flat base cushion type and self-aligning spherical cushion type. In addition, this kind of bearing can bear axial load, but cannot bear radial load.

Composition of thrust ball bearings: Thrust ball bearings are composed of 3 parts: seat ring, shaft ring, and steel ball cage assembly. The shaft ring matched with the shaft is called the seat ring matched with the shell.

Thrust ball bearing Type:
According to the force situation, it can be divided into one-way thrust ball bearing and two-way thrust ball bearing. One-way thrust ball bearings can bear a one-way axial load. Two-way thrust ball bearings can withstand two-way axial loads, in which the shaft ring is matched with the shaft. The mounting surface of the seat ring is a spherical bearing, which has self-aligning performance and can reduce the influence of installation errors. Thrust ball bearings cannot bear radial loads, and the limit speed is low.

Thrust ball bearing Features:

1. There are 2 types of one-way and two-way
2. In order to allow installation errors, whether it is one-way or two-way, you can choose the spherical self-aligning spherical seat cushion type or the spherical seat ring type.
3. High-quality steel – using ultra-clean steel that can extend bearing life by up to 80%
4. Advanced grease technology ― lubricant technology can extend the life of grease and improve the performance of bearings
5. High-grade steel balls – quiet and smooth when rotating at high speed
6. With the ferrule in the option, installation errors can be tolerated.

What Role do Seals and Shields Play in Protecting Ball Bearings from Dirt and Debris?

Seals and shields are critical components of ball bearings that play a crucial role in protecting them from dirt, debris, moisture, and contaminants in various applications. These protective features help maintain the integrity of the bearing’s internal components and ensure reliable operation. Here’s how seals and shields contribute to bearing protection:

Contaminant Exclusion:

Seals and shields create a physical barrier between the external environment and the bearing’s interior. They prevent dust, dirt, water, and other contaminants from entering the bearing and coming into contact with the rolling elements and raceways.

Lubrication Retention:

Seals and shields help retain lubrication within the bearing. They prevent the lubricant from escaping and contaminants from entering, ensuring that the bearing remains properly lubricated for smooth operation and reduced friction.

Corrosion Prevention:

Seals and shields protect bearing components from exposure to moisture and corrosive substances. By preventing moisture ingress, they help extend the bearing’s lifespan by minimizing the risk of corrosion-related damage.

Extended Bearing Life:

Seals and shields contribute to the overall longevity of the bearing by reducing wear and damage caused by contaminants. They help maintain a clean internal environment, which promotes proper rolling contact and minimizes the risk of premature failure.

Enhanced Performance in Harsh Environments:

In applications exposed to harsh conditions, such as outdoor machinery or industrial settings, seals and shields are vital. They protect bearings from abrasive particles, chemicals, and extreme temperatures, ensuring reliable performance despite challenging conditions.

Noise and Vibration Reduction:

Seals and shields can help reduce noise and vibration generated by the bearing. They provide additional damping and stability, contributing to smoother operation and enhanced user comfort in noise-sensitive applications.

Customized Protection:

Manufacturers offer a variety of seal and shield designs to suit different application requirements. Some seals provide higher levels of protection against contamination, while others are designed for high-speed or high-temperature environments.

Trade-Offs:

While seals and shields offer significant benefits, they can also introduce some friction due to contact with the bearing’s inner or outer ring. Engineers must balance the level of protection with the desired operating characteristics, considering factors like friction, speed, and environmental conditions.

Overall, seals and shields play a vital role in maintaining the integrity and performance of ball bearings. By effectively preventing contaminants from entering and preserving lubrication, they ensure the smooth and reliable operation of machinery and equipment in a wide range of applications.

How do Ball Bearings Differ from Other Types of Bearings like Roller Bearings?

Ball bearings and roller bearings are two common types of rolling-element bearings, each with distinct designs and characteristics. Here’s a comparison of ball bearings and roller bearings:

Design:

Ball Bearings: Ball bearings use spherical balls to separate and reduce friction between the bearing’s inner and outer rings. The balls enable rolling motion and smooth contact, minimizing friction.

Roller Bearings: Roller bearings, as the name suggests, use cylindrical or tapered rollers instead of balls. These rollers have larger contact areas, distributing loads over a broader surface.

Friction and Efficiency:

Ball Bearings: Due to the point contact between the balls and the rings, ball bearings have lower friction and are more efficient at high speeds.

Roller Bearings: Roller bearings have a larger contact area, resulting in slightly higher friction compared to ball bearings. They are more suitable for heavy-load applications where efficiency is prioritized over high speeds.

Load Capacity:

Ball Bearings: Ball bearings excel at handling light to moderate loads in both radial and axial directions. They are commonly used in applications where smooth rotation and low friction are important.

Roller Bearings: Roller bearings have a higher load-carrying capacity than ball bearings. They can support heavier radial and axial loads and are preferred for applications with significant loads or impact forces.

Variability:

Ball Bearings: Ball bearings come in various designs, including deep groove, angular contact, and thrust ball bearings, each suitable for different applications.

Roller Bearings: Roller bearings have diverse types, including cylindrical, spherical, tapered, and needle roller bearings, each optimized for specific load and motion requirements.

Speed Capability:

Ball Bearings: The reduced friction in ball bearings makes them suitable for high-speed applications, such as electric motors and precision machinery.

Roller Bearings: Roller bearings can handle higher loads but are generally better suited for moderate to low speeds due to slightly higher friction.

Applications:

Ball Bearings: Ball bearings are used in applications where smooth motion, low friction, and moderate loads are essential, such as electric fans, bicycles, and some automotive components.

Roller Bearings: Roller bearings find applications in heavy machinery, construction equipment, automotive transmissions, and conveyor systems, where heavier loads and durability are crucial.

In summary, ball bearings and roller bearings differ in their design, friction characteristics, load capacities, speed capabilities, and applications. The choice between them depends on the specific requirements of the machinery and the type of loads and forces involved.

Angular contact ball bearings are nonseparable bearings with a defined contact angle in the radial direction relative to the straight line that runs through the point where each ball makes contact with the inner and outer rings. In addition to radial loads, angular contact ball bearings can accommodate single direction axial loads. Since an axial load is generated from a radial force, these bearings are generally used in pairs. Typically ideal for machine tools, feed screw mechanisms, ball screw support units, etc.

Applications

Because they can bear heavy loads, angular contact bearings are used for heavy machinery and agricultural equipment. These bearings help run pumps, electric motors, gearboxes, steel mills, windmills, conveyors, and other high-speed applications.

Ball bearings and roller bearings are two common types of rolling-element bearings, each with distinct designs and characteristics. Here’s a comparison of ball bearings and roller bearings:

Design:

Roller Bearings: Roller bearings, as the name suggests, use cylindrical or tapered rollers instead of balls. These rollers have larger contact areas, distributing loads over a broader surface.

Friction and Efficiency:

Ball Bearings: Due to the point contact between the balls and the rings, ball bearings have lower friction and are more efficient at high speeds.

Load Capacity:

Variability:

Ball Bearings: Ball bearings come in various designs, including deep groove, angular contact, and thrust ball bearings, each suitable for different applications.

Roller Bearings: Roller bearings have diverse types, including cylindrical, spherical, tapered, and needle roller bearings, each optimized for specific load and motion requirements.

Speed Capability:

Ball Bearings: The reduced friction in ball bearings makes them suitable for high-speed applications, such as electric motors and precision machinery.

Roller Bearings: Roller bearings can handle higher loads but are generally better suited for moderate to low speeds due to slightly higher friction.

Temperature variations can affect the viscosity and flow characteristics of lubricants. Extreme temperatures can cause lubricants to become too thin or too thick, leading to inadequate lubrication and increased friction. In high-temperature environments, lubricants can degrade, reducing their effectiveness.

Material Properties:

Temperature changes can alter the material properties of the bearing components. High temperatures can lead to thermal expansion, affecting bearing clearances and potentially causing interference between components. Extreme cold temperatures can make materials more brittle and prone to fracture.

Clearance Changes:

Temperature fluctuations can cause changes in the internal clearance of ball bearings. For instance, at high temperatures, materials expand, leading to increased clearance. This can affect bearing performance, load distribution, and overall stability.

Corrosion and Contamination:

Harsh environmental conditions, such as exposure to moisture, chemicals, or abrasive particles, can lead to corrosion and contamination of bearing components. Corrosion weakens the material, while contamination accelerates wear and reduces bearing life.

Thermal Stress:

Rapid temperature changes can result in thermal stress within the bearing components. Differential expansion and contraction between the inner and outer rings can lead to stress and distortion, affecting precision and bearing integrity.

Noise and Vibration:

Temperature-related changes in material properties and internal clearances can influence noise and vibration levels. Extreme temperatures can lead to increased noise generation and vibration, affecting the overall operation of machinery.

Lubricant Degradation:

Environmental factors like humidity, dust, and contaminants can lead to premature lubricant degradation. Oxidation, moisture absorption, and the presence of foreign particles can compromise the lubricant’s performance and contribute to increased friction and wear.

Seal Effectiveness:

Seals and shields that protect bearings from contaminants can be affected by temperature fluctuations. Extreme temperatures can lead to seal hardening, cracking, or deformation, compromising their effectiveness in preventing contamination.

Choosing Appropriate Bearings:

When selecting ball bearings for specific applications, engineers must consider the expected temperature and environmental conditions. High-temperature bearings, bearings with specialized coatings, and those with enhanced sealing mechanisms may be necessary to ensure reliable performance.

Overall, understanding the impact of temperature and environmental conditions on ball bearing performance is crucial for proper bearing selection, maintenance, and ensuring optimal operation in diverse industries and applications.

What are the Different Components that Make up a Typical Ball Bearing?

A typical ball bearing consists of several essential components that work together to reduce friction and support loads. Here are the main components that make up a ball bearing:

Outer Ring:

The outer ring is the stationary part of the bearing that provides support and houses the other components. It contains raceways (grooves) that guide the balls’ movement.

Inner Ring:

The inner ring is the rotating part of the bearing that attaches to the shaft. It also contains raceways that correspond to those on the outer ring, allowing the balls to roll smoothly.

Balls:

The spherical balls are the rolling elements that reduce friction between the inner and outer rings. Their smooth rolling motion enables efficient movement and load distribution.

Cage or Retainer:

The cage, also known as the retainer, maintains a consistent spacing between the balls. It prevents the balls from touching each other, reducing friction and preventing jamming.

Seals and Shields:

Many ball bearings include seals or shields to protect the internal components from contaminants and retain lubrication. Seals provide better protection against contaminants, while shields offer less resistance to rotation.

Lubricant:

Lubrication is essential to reduce friction, wear, and heat generation. Bearings are typically filled with lubricants that ensure smooth movement between the balls and raceways.

Flanges and Snap Rings:

In some designs, flanges or snap rings are added to help position and secure the bearing in its housing or on the shaft. Flanges prevent axial movement, while snap rings secure the bearing radially.

Raceways:

Raceways are the grooved tracks on the inner and outer rings where the balls roll. The shape and design of the raceways influence the bearing’s load-carrying capacity and performance.

Anti-Friction Shield:

In certain high-speed applications, a thin anti-friction shield can be placed between the inner and outer rings to minimize friction and heat generation.

These components work together to enable the smooth rolling motion, load support, and reduced friction that characterize ball bearings. The proper design and assembly of these components ensure the bearing’s optimal performance and longevity in various applications.

How does Lubrication Impact the Performance and Lifespan of Ball Bearings?

Lubrication plays a critical role in the performance and lifespan of ball bearings. Proper lubrication ensures smooth operation, reduces friction, minimizes wear, and prevents premature failure. Here’s how lubrication impacts ball bearings:

Friction Reduction:

Lubrication creates a thin film between the rolling elements (balls) and the raceways of the bearing. This film reduces friction by separating the surfaces and preventing direct metal-to-metal contact. Reduced friction results in lower energy consumption, heat generation, and wear.

Wear Prevention:

Lubricants create a protective barrier that prevents wear and damage to the bearing’s components. Without proper lubrication, the repeated rolling and sliding of the balls against the raceways would lead to accelerated wear, surface pitting, and eventual failure.

Heat Dissipation:

Lubricants help dissipate heat generated during operation. The rolling elements and raceways can generate heat due to friction. Adequate lubrication carries away this heat, preventing overheating and maintaining stable operating temperatures.

Corrosion Resistance:

Lubrication prevents moisture and contaminants from coming into direct contact with the bearing’s surfaces. This helps protect the bearing against corrosion, rust, and the formation of debris that can compromise its performance and longevity.

Noise Reduction:

Lubricated ball bearings operate quietly because the lubricant cushions and dampens vibrations caused by the rolling motion. This noise reduction is crucial in applications where noise levels need to be minimized.

Seal Protection:

Lubricants help maintain the effectiveness of seals or shields that protect the bearing from contaminants. They create a barrier that prevents particles from entering the bearing and causing damage.

Improved Efficiency:

Properly lubricated ball bearings operate with reduced friction, leading to improved overall efficiency. This is especially important in applications where energy efficiency is a priority.

Lifespan Extension:

Effective lubrication significantly extends the lifespan of ball bearings. Bearings that are properly lubricated experience less wear, reduced fatigue, and a lower likelihood of premature failure.

Selection of Lubricant:

Choosing the right lubricant is essential. Factors such as speed, temperature, load, and environmental conditions influence the choice of lubricant type and viscosity. Some common lubricant options include grease and oil-based lubricants.

Regular Maintenance:

Regular lubrication maintenance is crucial to ensure optimal bearing performance. Bearings should be inspected and relubricated according to manufacturer recommendations and based on the application’s operating conditions.

In summary, proper lubrication is essential for the optimal performance, longevity, and reliability of ball bearings. It reduces friction, prevents wear, dissipates heat, protects against corrosion, and contributes to smooth and efficient operation in various industrial and mechanical applications.

Product Description

The inner and outer raceways of angular contact ball bearings are relatively offset from each other in the direction of the bearing. This means that such bearings are designed to carry a combined antenna, i.e. Bluetooth is added to the bearing axis.
On the bearing plane, the angle between the line connecting the contact points of the steel ball and the raceway (that is, the direction in which the combined tire is transported from 1 raceway to the other) and the vertical line of the bearing main axis.

Single row angular contact ball bearings can only bear axial load in 1 direction. When bearing radial load, additional axial force will be caused. And it can only limit the axial displacement of the shaft or housing in 1 direction. Angular contact ball bearings have a contact angle of 40 degrees and therefore can withstand large axial loads. Angular contact ball bearings are a non-separable design, with shoulders of different heights on both sides of the inner and outer rings. In order to increase the load capacity of the bearing, the shoulder on 1 side will be machined lower so that more steel balls can be loaded into the bearing.

China supplier Precise Axial and Radial Rigidity 7014 Angular Contact Ball Bearing double row ball bearing

Product Description

7014 Angular Contact Ball Bearing Introduction:
Angular contact ball bearings are specialized types of bearings designed to support both radial and axial loads simultaneously. And they are versatile components known for their ability to support combined radial and axial loads, making them essential in a wide range of mechanical systems and machinery.
7014 Angular Contact Ball Bearing key features and application:

Construction: Angular contact ball bearings typically consist of an inner ring, an outer ring, a cage (or separator), and rows of balls. The inner and outer rings have raceways, while the balls are positioned between them.
Contact Angle: Unlike deep groove ball bearings, which have a contact angle of 0°, angular contact ball bearings have a contact angle, usually between 15° and 40°. This angle allows them to support axial loads in addition to radial loads.
Types: Angular contact ball bearings come in several configurations, including single-row, double-row, and four-point contact bearings. Single-row bearings can accommodate axial loads in 1 direction, while double-row bearings can handle axial loads in both directions.
Preload: To optimize performance, angular contact ball bearings may be preloaded during installation. Preload applies a slight internal load to the bearings, which helps eliminate play and improve rigidity.
High-Speed Capability: Angular contact ball bearings are capable of operating at high speeds due to their design, which reduces friction and heat generation.
Applications: These bearings are commonly used in various industries, including automotive, aerospace, machine tooling, and robotics. They are suitable for applications such as wheel hubs, electric motors, pumps, and gearboxes, where both radial and axial loads are present.
Sealing Options: Depending on the application requirements, angular contact ball bearings may come with different sealing options, such as shields or seals, to protect against contaminants and retain lubrication.

What Factors should be Considered when Selecting a Ball Bearing for a Particular Application?

Selecting the right ball bearing for a specific application involves careful consideration of various factors to ensure optimal performance, longevity, and reliability. Here are the key factors that should be taken into account:

Load Type and Magnitude:

Determine the type of load (radial, axial, or combined) and the magnitude of the load that the bearing will need to support. Choose a bearing with the appropriate load-carrying capacity to ensure reliable operation.

Speed and Operating Conditions:

Consider the rotational speed of the application and the operating conditions, such as temperature, humidity, and exposure to contaminants. Different bearing types and materials are suited for varying speeds and environments.

Accuracy and Precision:

For applications requiring high accuracy and precision, such as machine tool spindles or optical instruments, choose high-precision bearings that can maintain tight tolerances and minimize runout.

Space Limitations:

If the application has limited space, choose miniature or compact ball bearings that can fit within the available dimensions without compromising performance.

Thrust and Radial Loads:

Determine whether the application requires predominantly thrust or radial load support. Choose the appropriate type of ball bearing (thrust, radial, or angular contact) based on the primary load direction.

Alignment and Misalignment:

If the application experiences misalignment between the shaft and housing, consider self-aligning ball bearings that can accommodate angular misalignment.

Mounting and Installation:

Consider the ease of mounting and dismounting the bearing. Some applications may benefit from features like flanges or snap rings for secure installation.

Lubrication and Maintenance:

Choose a bearing with appropriate lubrication options based on the application’s speed and temperature range. Consider whether seals or shields are necessary to protect the bearing from contaminants.

Environmental Conditions:

Factor in the operating environment, including exposure to corrosive substances, chemicals, water, or dust. Choose materials and coatings that can withstand the specific environmental challenges.

Bearing Material:

Select a bearing material that suits the application’s requirements. Common materials include stainless steel for corrosion resistance and high-carbon chrome steel for general applications.

Bearing Arrangement:

Consider whether a single-row, double-row, or multiple bearings in a specific arrangement are needed to accommodate the loads and moments present in the application.

By carefully evaluating these factors, engineers and designers can choose the most suitable ball bearing that aligns with the specific demands of the application, ensuring optimal performance, durability, and overall operational efficiency.
