Product features:

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.


Small ball design with excellent high-speed performance,high stiffness and low heat buildup. The material used for bearing rings is high purity SHX bearing steel with the special heat treatment process, cold treatment process and material modification technology, great improve the fatigue life of this series bearing.


Contact angle a choice between 30 degree (as in BAR series) and 40 degree (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 on radial load acting on the ball bearing, only axial load is allowed; the assembly method is back to back installation. The rolling element include: steel ball(BAR10S, BTR10S) and ceramic ball(BAR10H, BTR10H)


Speed factor:

BAR10S series

Great lubrication DmN≤750000 that the limiting speed N≤750000/Dm Dm—Bearing mean diameter Oil(minimum quantity) lubrication DmN≤950000


BTR10S series

Great lubrication DmN≤650000 that the limiting speed N≤650000/Dm Dm—Bearing mean diameter Oil(minimum quantity) lubrication DmN≤850000


BAR10H series

Great lubrication DmN≤850000 that the limiting speed N≤850000/Dm Dm—Bearing mean diameter Oil(minimum quantity) lubrication DmN≤850000


BTR10H series

Great lubrication DmN≤750000 that the limiting speed N≤750000/Dm Dm—Bearing mean diameter Oil(minimum quantity) lubrication DmN≤950000


Applications:

Using with cylindrical roller bearing, mainly used for high speed and high axial precision rotation and other conditions.
