Angular contact bearings can bear radial load and axial load. Able to work under high speed. Contact angle the greater the higher the axial load-bearing capacity. High-precision and high-speed bearings normally be admitted to the contact angle 15 degrees. Role in the axial force, the contact angle will increase. Single row angular contact ball bearings can only bear axial load in one direction, the radial load to bear, it will cause additional axial force. And can only limit the shaft or casing in a direction of axial displacement. If paired double-installed, so that a pair of bearing outer ring relative, that is, wide-side end face of wide and narrow side facing the narrow end. This will avoid the additional axial force, but also in both directions so that shaft or housing to limit the scope of the axial clearance |
