FAG Taper Roller ID 20mm, OD 42mm, W 15mm

Tapered roller bearings consist of solid outer and inner rings with tapered raceways and tapered rollers with cages. The bearings are not self-holding, 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 one-sided axial loads. A second bearing is usually necessary for axial support, which is then arranged in a mirror image. The different designs are marked by so-called suffix letters:
· A = modified internal design
· B = increased pressure angle
· X = outer dimensions adapted to international standards
· P5 = tolerance class.
