Great for Restoration

Used these to restore an old motor mount. They pressed in smoothly and have held up well under vibration. Highly recommend for precision work.

Good Steel Quality

The material quality is excellent. One sleeve had a very minor scratch on the OD, but it didn't affect performance. Good value for the price.

We use these in our workshop for jig fixtures. The tolerance is consistent across all pieces in the pack. Will order again.

Exact Dimensions

Measured these with digital calipers and they are spot on. Perfect fit for my lathe repair project. The hardened steel feels very durable.
