The angular contact ball bearings can undertake both the radial load and axial load in the mean-time. Such bearings can work at a high rotational speed. The bigger the touching angle is, the greater the bearing's load capacity is.
Angular contact ball bearings can bear radial load and axial load at the same time, (one-way angular contact bearings can only bear axial load in one direction, when bearing radial load, will cause additional axial force) the greater the contact Angle, the greater the load bearing capacity. High precision and high speed bearings usually take 15 degrees of contact Angle.
