I bought bearings to replace two worn bearings on my old Delta/Rockwell belt sander. They fit well and work perfectly. I'm taking off one star because of the mediocre quality. One stock had a bent shield and must have come from the factory as the box was undamaged. As I spin each bearing, they sound and feel different, possibly due to different amounts of grease or careless handling. The old bearings were made in Canada and although they are worn they look like they have been machined much better than new ones. The price was reasonable and came a day later than Revane promised, so four stars.
