Excellent durability

We have been running these in high dust environments. The graphite lubrication works well without attracting debris.

Perfect fit for our conveyor

Ordered the 30mm size. Fit was precise and installation was smooth. No lubrication needed so far.

Good quality, slight delay

The bushings are high quality copper alloy. Shipping took a day longer than expected but product is solid.
