The characteristic of the two-way thrust angular contact ball bearing is that it can bear the combined load of radial and axial loads at the same time, limiting the axial displacement of both sides of the shaft. It is composed of outer ring, inner ring, steel ball and cage, and can work stably at a higher speed. Attention should be paid to the installation, although the bearing can withstand two-way axial load, but if there is a ball gap on one side, it should be careful not to let the main axial load pass through the groove side of the gap.

The use of upper radial ball bearings and thrust ball bearings can not bear radial forces, and angular contact ball bearings can withstand both radial and axial forces.

Thrust ball bearings can withstand axial forces much more than angular contact ball bearings (about twice).

The accuracy of thrust angular contact ball bearings is much higher than that of thrust ball bearings, and the tolerable rotational speed is also much higher. It can be used as a spindle bearing.
