Silent operation
Replaced my noisy generic bearings with these. The difference in noise level is night and day. Highly recommended for precision setups.

Genuine THK Quality
Ordered the LMF16UU for a machine retrofit. The build quality is exceptional and motion is incredibly smooth. Definitely genuine THK product.

Fast shipping, good packaging
Arrived well protected in original packaging. One box had a minor dent but the bearing inside was unaffected. Will order again.

Great bearing, pricey
Performance is top notch as expected from THK. Only giving 4 stars because the price is significantly higher than generic alternatives, but you pay for reliability.

Perfect for linear actuators
Using these on a custom linear actuator project. The flange makes mounting very easy. No play or wobble detected.
Q: Do I need to add more grease before installation?
A: The units come pre-lubricated. However, depending on your application environment, periodic re-lubrication may be required over time.
Q: What is the load capacity for the LMF20 model?
A: Load capacities vary by specific bore size. Please refer to the official THK catalog for detailed dynamic and static load ratings for the LMF20UU.
Q: Are these manufactured in Japan or overseas?
A: These are genuine THK products manufactured in Japan, ensuring high precision and quality standards.
Q: Does the UU designation mean it has seals on both sides?
A: Correct, UU indicates that the bearing is equipped with double seals to protect against dust and debris ingress.
Q: Is this compatible with a hardened steel shaft?
A: Yes, these bearings are designed to be used with hardened and ground linear shafts for optimal performance and longevity.
