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 accommodate high radial and one-sided axial loads. Typically, a second bearing is required for axial support, which is then arranged symmetrically. The different designs are indicated by so-called suffixes: A = modified internal design, B = increased pressure angle, X = outer dimensions adapted to international standards, P5 = tolerance class. Special feature: modified internal design.
