Review on 🏎 High-Speed Koyo J 65 Bearings for 27000RPM Rotational Performance by Jake Powell

Revainrating 5 out of 5

Persistent; smooth

- This 3/8" bore needle bearing has a good, smooth and strong housing. I use it to help and align the arbor rotation of a small (3.25") circular saw and it works great Well.

Pros
  • bearing
Cons
  • unreliable
