China Good quality Thrust Ball Bearing/Skfnsk/51306/Ball Bearing/Roller Bearing/Rolling Bearing with Great quality

Product Description

Thrust ball bearings are a special type of ball bearing used to withstand axial thrust loads. Unlike conventional radial ball bearings, thrust ball bearings are mainly designed to transmit force in the axial direction, rather than withstand radial loads.

The thrust ball bearing consists of 1 or more ball race rings and a set of steel balls. The fairway ring is usually divided into a seat ring (seat ring) and a shaft ring (shaft ring), and the ball rolls between the 2 rings to transmit force. The design of thrust ball bearings enables them to withstand high axial loads while maintaining relatively low friction during high-speed rotation.

Thrust ball bearings are widely used in various mechanical equipment and systems, especially in applications that require handling axial thrust, such as automotive transmissions, clutches, motors, compressors, pumps, and fans. They are also commonly used in industrial machinery, aerospace, metallurgy, and energy applications.

Thrust ball bearings have advantages such as high load-bearing capacity, low friction, and high rotational speed, but their design and use also require selecting appropriate models, sizes, and lubrication methods based on specific application requirements.

What are the Differences between Deep Groove Ball Bearings and Angular Contact Ball Bearings?

Deep groove ball bearings and angular contact ball bearings are two common types of ball bearings, each designed for specific applications and load conditions. Here are the key differences between these two types of bearings:

  • Design and Geometry:

Deep Groove Ball Bearings:

Deep groove ball bearings have a simple design with a single row of balls that run along deep raceways in both the inner and outer rings. The rings are usually symmetrical and non-separable, resulting in a balanced load distribution.

Angular Contact Ball Bearings:

Angular contact ball bearings have a more complex design with two rows of balls, oriented at an angle to the bearing’s axis. This arrangement allows for the transmission of both radial and axial loads, making them suitable for combined loads and applications requiring high precision.

  • Load Carrying Capacity:

Deep Groove Ball Bearings:

Deep groove ball bearings are primarily designed to carry radial loads. They can handle axial loads in both directions, but their axial load-carrying capacity is generally lower compared to angular contact ball bearings.

Angular Contact Ball Bearings:

Angular contact ball bearings are specifically designed to handle both radial and axial loads. The contact angle between the rows of balls determines the bearings’ axial load-carrying capacity. They can handle higher axial loads and are commonly used in applications with thrust loads.

  • Contact Angle:

Deep Groove Ball Bearings:

Deep groove ball bearings have no defined contact angle, as the balls move in a deep groove along the raceways. They are primarily designed for radial loads.

Angular Contact Ball Bearings:

Angular contact ball bearings have a specified contact angle between the rows of balls. This contact angle allows them to carry both radial and axial loads and is crucial for their ability to handle combined loads.

  • Applications:

Deep Groove Ball Bearings:

Deep groove ball bearings are commonly used in applications that primarily require radial loads, such as electric motors, pumps, and conveyor systems. They are also suitable for high-speed operation.

Angular Contact Ball Bearings:

Angular contact ball bearings are used in applications where both radial and axial loads are present, such as in machine tools, automotive wheel hubs, and aerospace components. They are especially useful for applications that require precise axial positioning and handling of thrust loads.

  • Limitations:

Deep Groove Ball Bearings:

Deep groove ball bearings are not as suitable for handling significant axial loads and may experience skidding under certain conditions due to their deep raceways.

Angular Contact Ball Bearings:

Angular contact ball bearings can experience increased heat generation and wear at higher speeds due to the contact angle of the balls.

In summary, the design, load-carrying capacity, contact angle, and applications differ between deep groove ball bearings and angular contact ball bearings. Choosing the appropriate type depends on the specific load conditions and requirements of the application.
