Overview

FAG 30305-A Tapered Roller Bearing uses tapered rollers and raceways to handle combined radial and axial loads. It is commonly used in wheel hubs, gearboxes, industrial axles, and heavy equipment where shock load capacity and rigidity are required.

The inner ring, outer ring, tapered rollers, and cage are designed so their cone lines converge at a common point. A single-row bearing supports axial load in one direction, while paired mounting supports bidirectional axial load and preload settings.

Key features

Handles combined radial and axial loads
High rigidity and shock-load capability
Adjustable preload or endplay
Separable design for mounting and inspection

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.
