Good but packaging could be better

The bearings themselves are excellent quality. However, one box was slightly dented during shipping. Product was fine though.

5 FAQ

Q: What is the hardness of the steel used?

A: NSK bearings are typically made from high-carbon chrome steel with a hardness of approximately 60-64 HRC after heat treatment.

Q: Are these bearings suitable for high-speed applications?

A: These are standard deep groove bearings suitable for moderate to high speeds depending on the specific size and lubrication. Please check the technical datasheet for RPM limits.

Q: Is this product genuine NSK or a replica?

A: We guarantee 100% genuine NSK products sourced directly from authorized distributors. You can verify authenticity via the NSK portal.

Q: Does this come with rubber seals or metal shields?

A: The listing includes options for both ZZ (metal shield) and 2RS (rubber seal). Please select your preference from the dropdown menu before ordering.

Q: Can I use these for automotive wheel hubs?

A: While these are high quality, wheel hubs often require specific angular contact or tapered roller bearings. Please consult your vehicle manual for the correct bearing type.
