Good quality, precise dimensions

Dimensions matched the spec sheet perfectly. Fit was snug. Only giving 4 stars because shipping took a bit longer than expected.

Self lubricating feature is a lifesaver

Reduces maintenance time significantly. No need to grease frequently. Great replacement for our old copper bushings.

Perfect for high load applications

Installed these on our hydraulic press. The graphite impregnation works well without extra oil. Very satisfied with the durability.
