Product Introduction

The TRA0607 is a precision compact tapered roller bearing designed to provide substantial load-carrying capacity in space-constrained applications. With exact dimensions of 30 x 72 x 20.75 mm, it is frequently utilized in automotive steering systems, light differentials, and compact industrial gear motors. Produced with ultra-clean GCr15 bearing steel, the TRA0607 ensures minimal heat generation and long fatigue life. Our factory’s automated grinding and assembly lines guarantee strict dimensional consistency, offering B2B distributors a high-performance, vibration-free bearing solution.

Applications

Automotive steering column mechanisms.
Light utility vehicle wheel hubs and gearboxes.
Compact industrial speed reducers and motors.

FAQ

Q: Is the TRA0607 pre-lubricated?
A: Standard tapered roller bearings are supplied coated in anti-rust oil and require appropriate greasing or oil bath lubrication prior to operation.
Q: Can this replace standard ISO bearings of the same size?
A: Yes, it is manufactured to exact industry tolerances for seamless drop-in replacement.
