Good bearing, slow ship

Product is excellent but delivery took longer than expected. The bearing itself works flawlessly.

Authentic product

Verified the laser etching. Quality is noticeably better than generic brands I have used in the past.

Great for CNC axis

Smooth operation on my milling machine conversion. Fits the 12mm shaft perfectly with no binding.

Zero play

Installed on a 3D printer gantry. No wobbling at all. Very satisfied with the precision.
