Single Row Tapered Roller Bearing

A separable bearing with tapered rollers and raceways, designed for combined radial and axial loading. The inner ring, roller and cage assembly can be mounted separately from the outer ring.

For axial loading in both directions, single row bearings are used in a suitable paired arrangement. Confirm the operating clearance or preload for the application.
