Angular contact ball bearing
Product Description
Angular contact ball bearing:
The characteristic of this type of bearing is that the contact angle is not zero. A large contact angle indicates a great axial load capacity of the bearing. But a smaller contact angle is favorable for high-speed rotation.This type of bearing is mainly applied on high-speed, high precision and little axial load occasions, such as airplane engine main shaft, machine tool main shaft and main shafts of other high-speed precision machine. It can also be applied on high frequency motor, steam turbine, oil pump, air compressor and printing machine etc. it is one of the bearings most widely used machinery industry.
Angular contact ball bearing can be subjected to both radial and axial load. It can work in a high speed. The bigger contact angular, the higher axial load. High-precision and high-speed bearing is normally the contact angle of 15 degrees. The contact angle will increase by carrying the axial force. Single row angular contact ball bearing can only bear one axial load and will cause additional axial force when it is subjected to radial load. If installed in pairs and the bearing outer ring is relative, that is, wide face to wide face and narrow face to narrow face, which can avoid additional axial force, but also can limit the shaft within clearance in the two directions.
