Smooth operation

Very smooth sliding motion right out of the box. The flange helps with alignment significantly.

Perfect for linear actuators

Used these for a custom CNC build. The self-lubricating feature saves maintenance time. Fit was precise within tolerance.

Reliable supplier

Ordered bulk quantities. Consistency across the batch was good. One unit had a minor burr on the flange edge but easily filed down.

Good quality, slight delay

Material feels robust. Bronze layer is consistent. Shipping took 3 days instead of 1, but product is solid.

Excellent replacement bushings

Replaced worn-out metal bushings in our conveyor system. No more grease guns needed. Highly recommend for high-cycle apps.
