Bearing, 6001-2RS

The 12 mm inner diameter fits my mini lathe's intermediate shaft perfectly, and the deep groove design holds grease much better than the old one. It spins smoothly with no wobble at all.

Pulled the old bearing out of my mini lathe's intermediate shaft, and this 6001-2RS dropped right in with zero fuss. The 12 mm inner diameter was spot-on, and the rubber seals feel like they'll keep the grit out for a long time.

The 28 mm outer diameter lined up perfectly with the existing housing on my mini lathe, and the 8 mm width seated flush without any shims. It spins smooth and quiet under load, though I’d have liked a bit more grease packed in from the factory.
