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 one 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 two 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.
The following are the parameters for thrust ball bearings:
