Perfect for CNC Upgrade
Installed these on my CNC router X-axis. The motion is incredibly smooth and the flange mounting made installation straightforward. Highly recommend for hobbyist machines.

Solid Construction
Heavy duty feel to the metal. Packaging could have been better to prevent scratches, but the product itself works great on my linear rails.

Exactly as Described
Ordered the LMK12 size for a 3D printer project. Dimensions matched the spec sheet perfectly. No play in the bearing and the seals keep dust out.

Smooth Operation
Very quiet during operation. I was worried about noise but these run silently under load. The threaded holes are well tapped.

Good Quality, Tight Fit
The bearings are well made and feel sturdy. They were a bit tight on the shaft initially but loosened up after some use. Good value for the price.
Q: Can these be used in dusty environments?
A: The UU double rubber seals provide basic dust protection. For heavily dusty environments, additional wipers or covers are recommended.
Q: What screw size fits the LMK16 flange holes?
A: For the LMK16 model, the threaded mounting holes typically accept M5 screws. Please verify with a caliper upon receipt.
Q: What shaft hardness is recommended for these bearings?
A: We recommend using hardened and ground shafts with a minimum hardness of 50 HRC for optimal lifespan and performance.
Q: Are these metric or imperial measurements?
A: All LMK series bearings use metric measurements for bore, outer diameter, and mounting holes.
Q: Do these come pre-lubricated?
A: Yes, all LMK-UU series bearings are packed with grease at the factory. Additional lubrication may be needed depending on usage intensity.
