Genuine German Standard
Matches the specifications perfectly. I have used other brands before, but the MUH series holds tolerance much better under load. Very satisfied with this purchase.

Good Quality, Tight Fit Initially
The build quality is solid and feels genuine. They were a bit tight on the shaft at first but loosened up after some break-in motion. Good value overall.

Excellent Precision for CNC Build
Used these bearings for my CNC router project. The smoothness is outstanding and the center flange made mounting very straightforward. Highly recommend for precision work.

Solid Choice for Automation
Works well for my linear motion setup. The noise level is very low even at higher speeds. Price is slightly higher than generic options but worth it for reliability.
Q: Are these compatible with hardened steel shafts?
A: Yes, these bearings are designed to be used with hardened steel shafts rated at approximately 60HRC for optimal lifespan and performance.
Q: What is the difference between LMK and LMKC models?
A: The LMKC series features a center flange design, whereas the standard LMK typically has a different flange configuration. Please check your mounting requirements.
Q: What is the maximum operating temperature?
A: The rated operating temperature range is between -20°C to 100°C. Exceeding this may affect the lubricant and seal integrity.
Q: What is the tolerance range for the inner diameter?
A: The inner diameter follows standard ISO tolerance for linear ball bearings to ensure a smooth sliding fit on the shaft.
Q: Do I need to add extra lubrication before use?
A: No, the bearings come pre-lubricated with high-grade grease from the factory. You can install and use them immediately.
