Tapered roller bearings consist of solid outer and inner rings with tapered raceways and tapered rollers with cages. The bearings are not self-retaining, allowing the inner ring with the rollers and cage to be installed separately from the outer ring. Tapered roller bearings can handle high radial and unidirectional axial loads. Typically, a second bearing is required for axial support, which is arranged in a mirror image. The different versions are designated by so-called suffixes:
· A = Modified internal design
· B = Increased pressure angle
· X = Outer dimensions adapted to international standards
· P5 = Tolerance class.
