Perfect for my 3D printer

These bearings fit perfectly on my NEMA 17 motors. Smooth rotation and very quiet operation.

Good quality, slow shipping

The bearings themselves are excellent quality and spin freely. Only downside was the delivery took a bit longer than expected.

Smooth and low noise

Using these for a small robotics project. They handle the load well and produce minimal friction noise.

One was slightly stiff

Most of the pack was great, but one bearing out of the ten felt a bit gritty. Still usable for low speed applications.

Exactly as described

Ordered the MF85ZZ model and received exactly what was listed. Dimensions match my calipers perfectly.

5 FAQ

Q: Is the metal shield removable for cleaning?

A: No, the ZZ metal shields are non-removable. If you require removable seals for maintenance, please look for our open or rubber-sealed variants.

Q: Are these suitable for high RPM applications?

A: These are standard precision bearings suitable for moderate RPMs typical in motors and rollers. For extremely high speeds, please consult specific speed ratings.

Q: Can I use these for skateboard wheels?

A: No, these are miniature flanged bearings. Skateboards typically require 608 series bearings without flanges.

Q: Do they come pre-lubricated?

A: Yes, all bearings in this series come pre-greased from the factory and are ready for installation.

Q: What is the flange thickness on the MF62 model?

A: The flange thickness for the MF62 model is typically 0.6mm. Please refer to the detailed dimension chart in the product images.
