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.
Q: Do you sell matching linear shafts?
A: Yes, please check our Linear Shafts category for compatible hardened rods in various diameters.
Q: Can I use these in a dusty environment?
A: The double rubber seals provide good protection against dust, but regular maintenance is suggested for harsh environments.

Q: What is the recommended shaft tolerance?
A: We recommend using a shaft tolerance of g6 for optimal performance and longevity.
Q: Are these bearings metric or imperial sizes?
A: All LM series bearings listed here are metric sizes designed for metric linear shafts.
