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.

  • 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.

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.

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.

What are the Common Signs of Wear or Damage in Ball Bearings that Indicate the Need for Replacement?

Ball bearings are subjected to wear and stress during operation, and over time, they may exhibit signs of damage or deterioration that warrant replacement. Recognizing these signs is crucial to prevent catastrophic failure and ensure safe and reliable operation. Here are the common signs of wear or damage in ball bearings:

  • Unusual Noise:

If you hear unusual grinding, clicking, or rumbling noises coming from the bearing during operation, it may indicate worn-out or damaged components. Unusual noise suggests that the bearing is no longer operating smoothly.

  • Vibration:

Excessive vibration in the machinery can be a sign of bearing wear. Vibrations can result from uneven wear, misalignment, or damaged components within the bearing.

  • Increased Temperature:

Higher operating temperatures than usual may indicate increased friction due to inadequate lubrication, wear, or other issues. Monitoring the bearing’s temperature can help identify potential problems.

  • Irregular Movement:

If you notice irregular movement, jerking, or sticking during rotation, it could be a sign that the bearing is no longer operating smoothly. This may be due to damaged rolling elements or raceways.

  • Reduced Performance:

If the machinery’s performance has decreased, it may be due to a compromised bearing. Reduced efficiency, increased energy consumption, or a decline in overall performance could be indicators of bearing wear.

  • Visible Wear or Damage:

Inspect the bearing for visible signs of wear, such as pitting, scoring, or discoloration on the rolling elements or raceways. Severe wear or damage is a clear indication that the bearing needs replacement.

  • Leakage or Contamination:

If there is evidence of lubricant leakage, contamination, or the presence of foreign particles around the bearing, it suggests that the seal or shield may be compromised, leading to potential damage.

  • Looseness or Excessive Play:

If you can feel excessive play or looseness when manually moving the bearing, it could indicate worn-out components or misalignment.

  • Reduced Lifespan:

If the bearing’s expected lifespan is significantly shorter than usual, it may be due to inadequate lubrication, excessive loads, or improper installation, leading to accelerated wear.

  • Frequent Failures:

If the bearing is consistently failing despite regular maintenance and proper use, it could indicate a chronic issue that requires addressing, such as inadequate lubrication or misalignment.

It’s important to conduct regular inspections, monitor performance, and address any signs of wear or damage promptly. Replacing worn or damaged ball bearings in a timely manner can prevent further damage to machinery, reduce downtime, and ensure safe and efficient operation.

Are there any Industry Standards or Certifications that Ball Bearings should Meet?

Yes, there are several industry standards and certifications that ball bearings should meet to ensure their quality, performance, and reliability. These standards help manufacturers, engineers, and customers assess the suitability of bearings for specific applications. Some of the key standards and certifications for ball bearings include:

  • ISO Standards:

The International Organization for Standardization (ISO) has developed a series of standards related to ball bearings. ISO 15 defines dimensions, boundary dimensions, and tolerances for radial bearings. ISO 281 specifies dynamic load ratings and calculation methods for bearings’ life calculations.

  • ABEC (Annular Bearing Engineering Committee) Ratings:

ABEC ratings are commonly used in North America to indicate the precision and performance of ball bearings. Ratings range from ABEC 1 (lowest precision) to ABEC 9 (highest precision). However, it’s important to note that ABEC ratings focus primarily on dimensional tolerances and do not encompass all aspects of bearing quality.

  • DIN Standards:

The German Institute for Standardization (Deutsches Institut für Normung, DIN) has published various standards related to ball bearings. DIN 625 covers dimensions for deep groove ball bearings, while DIN 616 provides guidelines for precision angular contact ball bearings.

  • JIS (Japanese Industrial Standards):

JIS standards are used in Japan and internationally to define the characteristics and dimensions of various products, including ball bearings. JIS B 1512 outlines the classification and dimensions of rolling bearings.

  • ASTM (American Society for Testing and Materials) Standards:

ASTM has standards that cover various aspects of bearing testing, performance, and materials. ASTM F2215, for instance, specifies the requirements for ball bearings used in surgical implants.

  • CE Marking:

CE marking indicates that a product complies with European Union health, safety, and environmental requirements. It may be required for bearings used in machinery intended to be sold within the EU market.

  • Industry-Specific Standards:

Various industries, such as aerospace, automotive, medical, and nuclear, have specific standards or certifications that bearings must meet to ensure safety, reliability, and compliance with industry-specific requirements.

  • Quality Management Systems:

Manufacturers that adhere to quality management systems, such as ISO 9001, demonstrate their commitment to consistent product quality and customer satisfaction. Certification to these systems indicates that the manufacturing process follows established protocols and best practices.

When selecting ball bearings, it’s important to consider the relevant standards and certifications that align with the application’s requirements. This ensures that the bearings meet recognized quality and performance criteria, ultimately contributing to reliable and efficient operation.

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.

Preloaded bearings are stiffer due to the elimination of internal clearance. This increased stiffness improves the bearing’s ability to handle axial and radial loads with higher accuracy and minimal deflection.

  • Minimized Axial Play:

Preload minimizes or eliminates axial play within the bearing. This is especially important in applications where axial movement needs to be minimized, such as machine tool spindles and precision instruments.

  • Enhanced Rigidity:

The stiffness resulting from preload enhances the bearing’s rigidity, making it less susceptible to deformation under load. This is critical for maintaining precision and accuracy in applications that require minimal deflection.

  • Reduction in Ball Slippage:

Preload reduces the likelihood of ball slippage within the bearing, ensuring consistent contact between the rolling elements and the raceways. This leads to improved efficiency and better load distribution.

  • Improved Running Accuracy:

Preloading enhances the running accuracy of the bearing, ensuring that it maintains precise rotational characteristics even under varying loads and speeds. This is essential for applications requiring high accuracy and repeatability.

  • Optimized Performance at High Speeds:

Preload helps prevent skidding and slipping of the rolling elements during high-speed operation. This ensures that the bearing remains stable, reducing the risk of noise, vibration, and premature wear.

  • Impact on Friction and Heat Generation:

While preload reduces internal clearance and friction, excessive preload can lead to higher friction and increased heat generation. A balance must be struck between optimal preload and minimizing friction-related issues.

  • Application-Specific Considerations:

The appropriate amount of preload depends on the application’s requirements, such as load, speed, accuracy, and operating conditions. Over-preloading can lead to increased stress and premature bearing failure, while under-preloading may result in inadequate rigidity and reduced performance.

Overall, preload plays a critical role in optimizing the performance, accuracy, and efficiency of ball bearings. Engineers must carefully determine the right preload level for their specific applications to achieve the desired performance characteristics and avoid potential issues related to overloading or inadequate rigidity.

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.
