The load carrying capacity of spherical roller bearings is mainly used to bear radial loads. But it can also carry a certain amount of axial load in either direction. When the radial clearance of the bearing increases within a certain range, this bearing has the characteristics of an angular contact ball bearing, and can also bear a large axial load.

Compared with other types of bearings of the same size, spherical roller bearings have small friction losses, high limit speeds, and thrust ball bearings are not suitable for higher levels. speed. In this case, these bearings can be used for purely axial loads. If you increase the manufacturing precision and use strong cages of bakelite, bronze, duralumin and other materials, the RPM can also be increased.
