Overview

Tapered roller bearings from Western Bearing House

Tapered (taper) roller bearings have conical rollers and raceways whose lines meet on the bearing axis, so they carry combined radial and axial loads. They are normally mounted in pairs adjusted against each other, and are supplied in standard, wide and steep-angle series, metric and inch.
