  Angular contact ball bearing

Angular contact ball bearings include: 7000C (｜=15 °), 7000AC (｜=25 °) and 7000B (｜=40 °). The locking port of this kind of bearing is on the outer ring. Generally, the inner and outer rings cannot be separated, and can bear the combined radial and axial loads as well as the axial load in one direction. The ability to bear axial load is determined by the contact angle. The larger the contact angle, the higher the ability to bear axial load. The bearing can limit the axial displacement of the shaft or housing in one direction. The limit speed of contact ball bearing is relatively high. It can bear both radial load and axial load, as well as pure axial load. Its axial load capacity is determined by contact angle and increases with the increase of contact angle.
