British-system Single-row
Tapered Roller Bearing
bore 190,475-216,713mm
British-system single-row tapered roller bearing can be separated from the inner ring and roller, cage outer ring components together. And outer ring can be installed separately. Installation is more convenient, save time and effort. Modified contact lines for roller and raceway contact surfaces can reduce stress concentration. Since tapered roller bearings can only transfer unidirectional axial load, another symmetrical tapered roller bearing is needed to transfer the axial load in the opposite direction.
