Overview

Tapered roller bearing

Tapered roller bearings are designed so the conical rollers and the inner/outer raceways meet at a common apex, efficiently carrying large radial loads together with axial load in one direction. Typically mounted in opposed pairs to handle loads in both directions and provide rigidity, they are standard in automotive wheel hubs, transmissions and construction/mining equipment for heavy-duty service.

Key features

Large radial plus single-direction axial load
Opposed pairs give bidirectional load and rigidity
Separable for easy mounting and adjustment
Standard in heavy-duty drivetrains

Typical applications

Automotive and industrial wheel hubs
Gearboxes and differentials
Construction and agricultural axles
Conveyors and rolling equipment

Selection guidance

Consider load ratio, mounting direction, preload/endplay, lubrication, and the paired bearing arrangement.
