This type of bearings is separable and the contact angle is 90 degree.So the bearings can only carry axial load. While the bearings runing, the balls are extruded to the outside of raceway by centrifugal effect and easy to be scraped. So this typy of bearing can not be used under the high speeds condition. The single direction bearings of them can only carry axial load in one direction, while the double can carry alternating axial load in either direction.And the trust ball bearings with spherical outer ring have self-aligning functions. Furthermore, the bearings have a capacity of axial space limiting,and also do a little to the radial space limiting.
Its structure: The material of bearing cages can be devided into copper and stainless steel. The material of bearing gasket is bearing steel or stainless steel.
