Perfect fit for our hydraulic press
We ordered these liners for a refurbishment project. The dimensions were precise and the material quality is evident. No issues during installation.

Excellent wear resistance
Been using these in high-friction environments for over 6 months. They show minimal wear compared to previous suppliers. Highly recommended.

Good quality, slight delay
The product itself is top notch and machined well. Shipping took a few days longer than expected, but the quality makes up for it.

Custom dimensions were spot on

Q: Do you offer bulk discounts for orders over 50 units?
A: Yes, we provide tiered pricing for bulk orders. Please contact our sales team directly for a customized quote.
Q: Can you modify the inner diameter to 75mm?
A: Yes, we offer custom machining services. Please submit your technical drawings for a feasibility check and quote.
Q: What type of lubrication is recommended for installation?
A: Standard industrial grease or oil suitable for copper alloys is recommended to ensure smooth operation and reduce initial friction.
