Roller bearings are bearings in which two components that move relative to each other – the so-called inner ring and outer ring – are separated by rolling elements.
Axial spherical roller bearings
The structure of axial spherical roller bearings is similar to that of radial spherical roller bearings; however, only one row of rolling elements is used. The spherical form of the raceways allows both high axial loads to be absorbed and alignment errors to be corrected.
