Smooth, Quiet, and Reliable

After installing, I spun the hub by hand—zero drag or roughness. Paired with synthetic grease, it’s running cooler than the old unit. A small part, but critical for safety.

Consistent with Timken Standards

I inspect every component I install. This race has a clean, ground finish and true roundness. Verified outer diameter with micrometer—3.265" exactly. That’s the kind of precision I expect.

Dependable and Accurately Labeled

Marked clearly with "25520" on the edge—makes inventory easy. Press-fit design seated fully with a bearing installer tool. No wobble or misalignment during spin test.

Smooth Operation After Rebuild

Did a full hub service on my horse trailer. This race installed cleanly and runs cool even after long drives. No vibration or heat buildup. Precision matters at highway speeds.

Used in Emergency Repair – Worked Flawlessly

Popped a race 150 miles from home. Ordered overnight, got it by noon. Installed it at a shop and was back on the road same day. Matched my 8-213-5 hub perfectly. Lifesaver.
