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.
Q: What is the lead time for bulk orders over 100 units?

Q: Does this come with a warranty?
A: Yes, all our bearings come with a standard 30-day manufacturer defect warranty.
Q: Can I cut this bushing to a shorter length?
