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.
