Product Description

This Koyo/JTEKT trailer axle bearing kit includes the inner and outer tapered roller bearing cone and race sets commonly used on most 7,000 lb trailer axles.

Koyo/JTEKT single row tapered roller bearings are designed with tapered rollers and conical raceways, allowing them to support combined radial and axial loads in one direction. The cone assembly consists of the inner ring, cage, and roller set, while the cup is the outer race.

These bearings are open-design tapered roller bearings and are commonly mounted in pairs or mirror-image arrangements depending on the application.

Premium Japanese quality. Manufactured by Koyo/JTEKT.
