Q: Which type is belonging to an angular contact bearing?

Single-row angular contact ball bearings can only bear axial loads in one direction, and they will cause additional axial forces when bearing radial loads. And can only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are non-separated design, with shoulders on both sides of the inner and outer rings varying in height. In order to increase the load capacity of the bearing, the shoulder on one side is processed lower, so that the bearing can fit more steel balls.

Double-row angular contact ball bearings can withstand large radial and axial combined radial and axial loads and moment loads, limiting axial displacement on both sides of the shaft. Mainly used to limit the axial displacement of the shaft and the shell in the two-way angular contact ball bearing. The tiltability between the inner and outer rings is limited. The allowable tilt angle depends on the internal clearance of the bearing, the size of the bearing, the internal design and the effect The force and moment on the bearing, and the maximum allowable tilt angle should ensure that no excessively high additional stress is generated in the bearing. If there is an inclination angle between the inner and outer rings of the bearing, it will affect the life of the bearing, at the same time, it will reduce the bearing running accuracy and increase the running noise. Double-row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, care should be taken. Although the bearing can withstand bidirectional axial loads, if there is a ball gap on one side, care should be taken not to let the main axial load pass through the groove side of the gap. When using bearings, care should be taken to make the raceway on the side without the ball notch bear the main load.
