Great for motors

Running cool under load. I appreciate the metal shields as they keep the grease in and dust out effectively.

Precise fit for my project

Measured the dimensions with calipers and they are spot on according to the GB standard. Smooth rotation right out of the box.

Smooth spin

Very quiet running bearings. I used them for a small electric motor upgrade and the noise level dropped significantly.

Good quality

The bearings themselves are excellent. Packaging could be a bit more robust to prevent shifting during shipping, but no damage occurred.

5 FAQ

Q: Do you offer bulk discounts for 100 packs?

A: Yes, please contact our sales team directly through the messaging system for bulk pricing on large quantity orders.

Q: Are these bearings made of stainless steel?

A: No, these are made of GCr15 bearing steel which is hardened for durability. They are not corrosion-resistant like stainless steel.

Q: What is the maximum RPM for the 695 size?

A: For the 695 model, the limiting speed is approximately 34,000 RPM with grease lubrication under ideal conditions.

Q: Is the grease suitable for high temperatures?

A: The standard grease works well between -20°C and 120°C. For higher temperatures, special lubrication may be required.

Q: Can I remove the ZZ shields to clean them?

A: The ZZ metal shields are non-removable. If you need removable seals, please look for our RS or 2RS rubber seal options.
