Quiet movement
Much quieter than my old bearings. The double seals seem to keep dust out effectively. Will be ordering more for my next project.

Good value
Works well but came with extra grease on the outside. I had to clean them before installation. Otherwise, performance is solid.

Perfect fit
Ordered the LMF12LUU size for my 3D printer build. They slid onto the shafts perfectly without being too loose. Great quality for the price.

Smooth operation
Used these for my CNC router upgrade. The motion is incredibly smooth and there is no play in the bearing. Highly recommend for precision work.

Reliable supplier
Third time ordering these linear bearings. Consistency is key for me and these deliver every time. Shipping was fast too.
Q: Do these come with lubrication or do I need to add grease?
A: Yes, they are pre-lubricated with grease from the factory. You can add more later if needed depending on usage.
Q: What shaft tolerance do you recommend for these bearings?
A: We recommend using hardened linear shafts with h6 or g6 tolerance for optimal performance and longevity.
Q: Can I use these on soft steel shafts?
A: We recommend hardened shafts specifically. Using soft shafts may cause wear on the shaft and reduce bearing life.
Q: What is the mounting hole pattern for the LMF20LUU?
A: It varies by size. Please refer to the dimensional chart in the product images for specific mounting hole distances.
Q: Is the flange removable if I need a straight bearing?
A: No, the flange is integrated into the bearing housing and cannot be removed. Please select a straight type if flange is not needed.
