Angular Contact Ball Bearings 7213B
1.Low noise and vibration
2.High accuracy
3.Reasonable price

Single  row  angular contact  ball bearing not only bears the radial load and axial load at the same time but also the pure axial load. It can work under high speed and can only bear axial load in one direction. The axial load capacity is determined by contact angle. Axial load capacity is high if contact angle is large, but it is more conducive to high-speed rotation if the contact angle is smaller. The contact angle is defined as, the angle between the radial line in the plane connecting ball and raceway contact and the line vertical axis
