Great value
Bought the LM20 size. Fit is precise and matches standard shafts perfectly. Good price point for imported quality.

Reliable imported quality
Consistent quality across multiple orders. We use these for light automation tasks and they hold up well.

Good but tight
Needed some break-in time before it slid freely. Now works well. Just be aware it might be stiff out of the box.

Perfect for 3D Printer
Replaced old bearings with these on my coreXY printer. Much quieter and smoother layers now.

Smooth operation for CNC
Works perfectly on my X-axis. Very smooth movement with minimal friction. Highly recommended for hobbyist CNC builds.
Q: Can I use this on a soft aluminum rod?
A: No, using on soft materials like aluminum will cause rapid wear. Please use hardened steel shafts.
Q: Do I need to add more grease upon arrival?
A: The unit comes pre-greased. You should maintain lubrication based on your specific usage frequency.
Q: What is the difference between UU and UUOP?
A: UUOP indicates an Open Type design, which allows for side mounting and adjustment on supported shafts.
Q: Is the size exact to metric standards?
A: Yes, these bearings follow standard ISO metric dimensions for LM series linear bushings.
Q: What shaft hardness is required for these bearings?
A: We recommend a shaft hardness of HRC50 or higher for optimal bearing life and performance.
