Series Overview

The BT, NP, TR and U series represent specialist inch tapered roller bearing families with application-specific designations used primarily in automotive, truck and specialist industrial equipment.

The BT1B prefix (SKF/FAG designation) denotes bearings produced to SKF internal standards. The NP prefix (Timken) and TR prefix identify matched tapered roller pairs for specific automotive differential and wheel end assemblies. The U/SET series are pre-matched cone-and-cup sets for wheel bearing applications. Supplied by GBC, MOQ 100 pieces.

Key Design Features

Automotive-grade matched sets

BT, NP, TR and U/SET bearings are precision-matched pairs, factory-selected to tight preload tolerances for wheel end and differential applications.

Specialist designation systems

BT1B (SKF), NP (Timken) and TR designations indicate bearings produced to manufacturer-specific internal standards.

Cross-reference to ABMA equivalents

Most BT, NP and U series bearings have ABMA equivalent designation numbers. Contact us for cross-reference information.

U/SET pre-matched wheel bearing assemblies

U-SET series (SET9, SET10, SET20, SET80) are pre-matched sets for truck and trailer wheel end applications.
