Fast shipping and well packed
Arrived quickly and were wrapped individually to prevent damage. No issues with fitment on standard linear shafts.

Excellent build quality
I ordered the 20LUU size for a linear motion project. The steel feels robust and the seals keep dust out effectively.

Good value
Solid bearings for the price. One of them was slightly stiff out of the box but loosened up after some use. Would buy again.

Reliable components
Using these for a custom automation rig. They handle the load well and movement is precise without much play.

Perfect for my CNC router
These bearings slide smoothly on my hardened shafts. The flange mounting holes lined up perfectly with my design. Very satisfied with the quality.
Q: Is the flange removable if I need a straight bearing?
A: No, the flange is integrated into the housing and cannot be removed. Please select a straight model if flange is not required.
Q: Are these compatible with standard hardened linear shafts?
A: Yes, these bearings are designed specifically for use with hardened and ground linear shafts.
Q: What is the tolerance range for the 10mm bore size?
A: The bore follows standard ISO tolerances for linear ball bearings suitable for g6 shaft tolerance.
Q: Do I need to add additional grease before installation?
A: They come pre-greased from the factory. However, regular maintenance lubrication is recommended for long-term use.
Q: Can these bearings support vertical mounting orientations?
A: Yes, they can be mounted vertically, but ensure the shaft is properly supported to prevent bending under load.
