Good quality, slight stiffness
Quality seems high. They were a bit stiff out of the box but loosened up after some use. Good for the cost.

Smooth operation on Z-axis
Installed these on my milling machine conversion. The motion is incredibly smooth and the flange mounting was straightforward.

Perfect fit for LM12 shafts
Ordered the LMH12UU set. They fit my hardened rods perfectly with no wobble. Great value for the price.
Q: Is the flange thickness standard across all sizes?
A: No, the flange dimensions scale with the bore size. Please refer to the dimension chart in the product images.
Q: Can I use these with unhardened steel shafts?
A: It is not recommended. Using unhardened shafts may cause premature wear on the bearing balls and raceway.
Q: What is the shaft tolerance required for these bearings?
A: We recommend using hardened shafts with a g6 tolerance for optimal performance and lifespan.
Q: What is the maximum operating temperature?
A: Standard seals are rated up to 80 degrees Celsius. High-temp options may be available upon request.
Q: Do these come pre-lubricated or do I need to add oil?
A: These bearings come pre-lubricated with standard grease. You can add more later if needed for specific applications.
