Smooth operation

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

5 FAQ

Q: Does this require additional grease during installation?

A: No, it is self-lubricating due to the PTFE layer, but a thin film of oil can help during initial press fit.

Q: What is the shaft tolerance recommendation for 70mm ID?

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.

Q: Do you offer bulk discounts for orders over 100 units?

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.
