High-Speed Angular Contact Thrust Ball Bearing
Structural features:
Small ball design, with excellent high-speed performance, high stiffness and low heat buildup
The material used for bearing ring is high purity SHX bearing steel, with a special heat treatment process, cold treatment process and material modification technology, greatly improve the fatigue life of this series of bearing.
Contact angle offers a choice between 30º (as in BAR series) and 40º (as in BTR series). Ball bearings in special widths are available. The bearing outer dimensional deviation is intentionally adjusted in order to create a clearance between the ball bearing and the pillow block it fits in. The result is no radial load acting on the ball bearing, only axial load is allowed; The assembly method is back to back installation.
Using the ball guided nylon cage, can long-term work stably less than 120ºС.
The rolling element include: Steel ball (BAR10S;BTR10S) and ceramic ball (BAR10H; BTR10H)

Applications:
Using with cylindrical roller bearing, mainly used for high-speed and high axial precision rotation and other conditions.
For example:
big wheel spindle of CNC universal grinding machine, CNC lathe spindle, centerless grinding wheel shaft, bearing raceway grinding wheel spindle, high-speed precision machinery, etc.
