Nickel plating is a nice touch

The rust-resistant coating gives me peace of mind in my workshop which can get humid sometimes. Quality feels solid.

Precise fit on shafts

Shaft tolerance seems accurate. I used h6 shafts and the fit was perfect without being too loose or too tight.

Smooth operation on gantry

Installed these on my CNC router gantry and the movement is incredibly smooth. No binding issues detected during initial testing.
