Angular contact ball bearing/shaft bearing/axle bearing/paired bearing
1. Description
Angular contact ball bearing can bear radial and axial load simultaneously, and work in high speed. The bigger the contact angle, the higher the load capacity. Bearing with high precision and speed usually take 15 contact angle. In axial force, the contact angle will increase.
Single-row angular contact ball bearing: It can only carry axial load from single direction, and additional axial force will be caused when carry radial load, and the shaft and housing are only restricted moved in one direction.
Double-row angular contact ball bearing: If paired bearings are installed, make a pair of outer ring opposite, that is wide faces and narrow faces are opposite separately, which can avoid additional axial force, and also limit shaft and housing into the axial clearance range in two direction.
