Great for lathe machinery

Installed these on my industrial lathe. They run smooth and quiet. No vibration issues so far after 2 weeks of heavy use.

Good value for money

Solid bearings. Packaging was secure. Only giving 4 stars because shipping took a day longer than expected.

5 FAQ

Q: Do these come pre-lubricated or do I need to add oil?

A: All bearings in this catalog come pre-greased from the factory. No additional lubrication is needed upon installation.

Q: Are these compatible with standard 6308 housings?
