Single row angular contact ball bearings can only bear axial load in one direction, when bearing radial load, will cause additional axial force. And can only limit the axial displacement of the shaft or shell in one direction.
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.
