Exact fit for restoration

Needed a non-standard size for an old engine rebuild. The 20mm ID fit perfectly on the shaft.

Solid industrial part

Meets specifications listed. Would prefer if OD options were more granular but these work.

Good quality, slow shipping

The bearing itself is high quality and runs smooth. Shipping took a bit longer than expected.
