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.
Q: Do I need to add lubrication before first use?
A: No, these bearings come pre-lubricated with grease from the factory. You can install and use them immediately.
Q: Is the price for a single unit or a pair?
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?
A: No, mounting screws are not included. Please purchase standard metric screws separately based on your flange hole size.
Q: What shaft hardness is recommended for these bearings?
A: We recommend using hardened linear shafts with a hardness of at least 55 HRC for optimal lifespan and performance.
Q: Can these be used in outdoor applications?
A: While they are sealed, prolonged exposure to moisture or harsh elements is not recommended without additional protective housing.
