Works Well
Functionality is great. There was a slight noise at first but it went away after lubrication. Shipping was fast and packaging protected the items well.

Solid Construction
Heavy duty feel and the seals keep dust out effectively. I use these in a dusty workshop environment and they have held up well over three months.

Good Quality, Tight Fit
The bearings are well-made and feel solid. They were a bit tight on the shaft initially but loosened up after some use. Good value for the price.

Exact Replacement
Needed these to replace worn-out bearings on an old automation rig. The dimensions matched perfectly and the flange mounting holes aligned without issues.

Perfect for CNC Upgrade
Installed these on my CNC router axis. The motion is incredibly smooth and the extended length provides great stability. Highly recommend for anyone looking to reduce vibration.
Q: What shaft hardness is required for these bearings?
A: We recommend using hardened linear shafts with a hardness of at least 58 HRC for optimal performance and longevity.
Q: Can I use these outdoors?
A: While they have rubber seals, they are not fully waterproof. We recommend protecting them from direct exposure to rain or moisture.
Q: Are these bearings pre-lubricated?
A: Yes, all units come pre-greased from the factory. You can add more lubrication later depending on your application needs.
Q: Do you sell matching linear shafts?
A: Yes, we carry a full range of hardened linear shafts that are compatible with this bearing series. Please check our related products section.
Q: What is the mounting hole pattern for the LMH20LUU?
A: For the 20mm model, the flange typically features 4 mounting holes with a PCD of 31mm and M5 thread size.
