Good bushing, tight fit

Quality is excellent, but required a bit more force to press in than expected. Still works great.

No more squeaking

Replaced an old worn bushing on my excavator arm. Silence is golden.

5 FAQ

Q: Is a certificate of conformity available?

A: Yes, please contact us directly after ordering to request documentation.

Q: What is the maximum shaft speed recommended?

A: For this size, we recommend max sliding speed of 0.5 m/s for continuous operation.

Q: What is the recommended press fit tolerance?

A: We recommend H7/p6 for optimal retention.

Q: Can this be used in underwater applications?

A: While oil-impregnated, prolonged submersion may wash out lubricant. Use sealed variants for water.

Q: Does this require additional greasing during installation?

A: No, it is self-lubricating. However, a light coat of oil on the OD helps installation.
