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.

Perfect replacement
Matched the old worn-out part exactly. Machine runs like new again. Highly recommend.

Zero play
Installed on a 3D printer gantry. No wobbling at all. Very satisfied with the precision.
Q: Is the flange removable for different mounting?
A: No, the flange is integrated into the bearing outer ring and cannot be removed.
Q: Is grease included or do I need to add it?
A: The unit comes pre-lubricated from the factory. Additional lubrication depends on usage intensity.
Q: Does this fit standard metric shafts?
A: Yes, this series is designed specifically for standard metric linear motion shafts.
Q: What is the return policy if the size is wrong?
A: Unused items in original packaging can be returned within 30 days of delivery.
Q: Can I use this with aluminum shafts?
A: No, these bearings require hardened steel shafts to prevent premature wear and damage.
