Smooth Operation

These bearings glide effortlessly on hardened shafts. I use them for a 3D printer project and noise levels are minimal.

Good Value

Solid construction for the price. Took a little bit of break-in time before becoming fully smooth, but works well now.

Perfect for CNC Machine

Ordered the 12mm size for my CNC router upgrade. The fit is smooth and the flange mounting was exactly what I needed. Very satisfied with the quality.

Exact Specifications

Measured the inner diameter and it matches the 20mm shaft perfectly. No wobble or play. Highly recommend for robotics.

Reliable Component

Bought multiple sizes for different projects. The sealing keeps dust out effectively. Will purchase again.

5 FAQ

A: No, these bearings come pre-lubricated with grease from the factory. You can install and use them immediately.

A: The listed price is for a single piece. If you need a pair, please adjust the quantity to 2 during checkout.

Q: Does this bearing come with mounting screws?
