Tapered roller bearings carry heavy combined radial and axial loads. The tapered geometry distributes load across the full roller length. Standard in wheel hubs, gearboxes, and heavy machinery. Must be adjusted for proper preload.
Use the Bearing Life Calculator to determine service life with Cr = 78.1 kN, or the Selection Wizard to compare alternatives. For shaft and housing tolerances, use the Fit Calculator with bore = 50 mm.

Dimensions and load ratings are typical catalog values. Always verify against the specific manufacturer catalog for your application. Variants (shielded -ZZ, sealed -2RS, clearance C3) have identical dimensions and load ratings.
