Solid build quality
Heavy duty feel. Packaging was minimal but the part arrived undamaged. Good value for the price.

Good quality, slight break-in needed
Quality seems high given the steel weight. Was a bit stiff out of the box but smoothed out after a few cycles.

Perfect fit for CNC upgrade
Installed these on my CNC router gantry. The 12mm size fits the shaft perfectly with no play. Motion is very smooth.

Exact replacement part
Replaced worn-out bearings on my 3D printer linear rail. These match the original specs exactly.

Very quiet operation
I was worried about noise but these run silently at moderate speeds. The flange mounting is sturdy.
Q: Are these compatible with hardened steel shafts?
A: Yes, these bearings are designed specifically for use with hardened and ground linear shafts.
Q: Is there a difference between LHFCD and LHFCDM?
A: LHFCDM typically denotes specific metric dimension variations, but both are flanged linear bearings.
Q: What is the dynamic load rating for size 20?
A: Please refer to the technical datasheet for specific load ratings per size, as they vary by diameter.
Q: How often should I re-lubricate these bearings?
A: Under normal conditions, we recommend re-lubrication every 100km of travel or every 6 months.
Q: Can these be mounted vertically?
A: Yes, they can be mounted vertically. Ensure the mounting bolts are tightened to specification to prevent slipping.
