Smooth operation
Reduced noise in my hydraulic press significantly. Very happy with the self-lubricating feature.

A: h9 tolerance is recommended for best fit and performance.
Q: Can this be used in submerged underwater applications?
A: Not recommended for continuous submerged use as it may affect the self-lubricating properties over time.

A: Yes, please contact our sales department directly for volume pricing tiers.
Q: What is the hardness rating of the bronze layer?
A: Typically 150-220 HB depending on the specific batch testing.
