Solid industrial bearings

Heavy duty feel and good construction. One bearing had a slight scratch on the outer case but did not affect performance.

Good value but tight fit

The bearings are well made, but the LM8 size was a bit tight on my shaft initially. After some break-in time, they work perfectly.

Smooth operation for CNC

Used these LM16 bearings for my CNC router upgrade. The motion is very smooth and there is no noticeable play. Great quality for the price.

Perfect for 3D printers

Exactly what I needed for my 3D printer build. The double seals keep dust out effectively. Shipping was faster than expected.

Reliable supplier

This is my second order from RYS. Consistent quality across different sizes. I ordered LM12 and LM20 this time.
