Perfect for my CNC router build

These bearings fit smoothly on the linear shafts. The flange mounting holes aligned perfectly with my machined plates. Very satisfied with the precision.

Reliable for automation projects

Using these in a custom pick and place machine. They handle the load well and movement is consistent. No binding issues so far.

Good quality, slightly tight fit initially

Quality seems high for the price. They were a bit stiff out of the box but loosened up after some movement. Good value overall.

Solid construction, needs greasing

The metal feels robust. I added some extra lubricant before installation for smoother operation. Works great on my 3D printer Z-axis.
