Good quality, slight delay
The bearings themselves are excellent quality stainless steel. One felt slightly tight out of the box but loosened up after use. Shipping took a bit longer than expected.

Excellent high-speed performance
Using the 697 model for a high RPM spindle. No heat buildup after continuous run. Great value for imported steel.

Quiet operation
I replaced the old bearings in my mini lathe with these. The noise level dropped significantly. They seem very durable too.

Genuine stainless steel
Tested these in a humid environment and there is no sign of rust after months of use. Exactly what I needed for my project.

Perfect for my drone build
These bearings are incredibly smooth. I used the 696 size for my motor mounts and the vibration is almost non-existent. Highly recommend for high-speed applications.
Q: What is the maximum RPM for the 697 model?
A: The maximum RPM varies based on load and lubrication, but the 697 is designed for high-speed applications typically exceeding 20,000 RPM under light load.
Q: Is the grease used in these bearings food safe?
A: No, the standard low-noise grease is for industrial and hobby use only. It is not certified for food contact applications.
Q: Can I use these bearings for skateboard wheels?
A: These are miniature bearings (693-699 series) and are too small for standard skateboard wheels, which typically require 608 size bearings.
Q: Do you offer bulk discounts for orders over 100 units?
A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly for a custom quote.
Q: Are these bearings waterproof?
A: While made of stainless steel which resists corrosion, they are not fully waterproof. The 2RS seal offers better protection against moisture than the ZZ shield.
