Good Value

Bearings are smooth and well-made. One rubber seal was slightly tight during installation but seated properly after use.

Great Precision

Used these for a spindle repair on my lathe. The fit was exact and the runout is minimal. Very satisfied with the German quality.

5 FAQ

Q: Do they come pre-lubricated?

A: Yes, all bearings in this set come pre-lubricated with standard grease suitable for general industrial applications.

Q: What is the difference between ZZ and RS seals?

A: ZZ indicates metal shields on both sides, while RS indicates rubber contact seals which offer better protection against dust and moisture.

Q: Can these handle high RPM applications?

A: Yes, the 6904 model is specifically rated for high-speed operations, but please check the specific size specs for max RPM limits.

Q: What is the return policy if the size is wrong?

A: We offer a 30-day return policy for unused items in original packaging. Please contact us for a return authorization.

Q: Is this a physical catalog book or the actual bearings?

A: This listing is for the actual bearings conforming to the 6900 series catalog standards, not a reference book.
