Sturdy construction

The copper layer feels solid. No deformation during install using a standard arbor press. Highly recommend.

Good for low speed

Works well for my pivot point application. Just note this is not for high RPM spinning, better for oscillating motion.

Exact Dimensions

Measured with calipers, spot on 30mm. Pressed in easily without damaging the lining. Great for my repair job.

No maintenance needed

Great for hard to reach spots where greasing is impossible. Saves me time on routine maintenance checks.
