Frequently Asked Questions
Q1: What is the main function of the KL51 piston seal?
A: The KL51 is a double-acting seal designed for hydraulic pistons, providing low friction and high sealing performance in mobile machinery.
Q2: Can these seals handle high-pressure environments?
A: Yes, the KL51 seals are designed to withstand pressures up to 400 Bar.
Q3: What materials are used in the construction of KL51?
A: It consists of a high-performance PTFE sealing ring and an NBR elastomer energizer profile ring.
Q4: What is the lead time for order delivery?
A: Standard delivery typically ranges from 7 to 15 working days depending on the order size.
Q5: Are these seals suitable for construction machinery?
A: Absolutely. They are ideal for excavators, forklifts, cranes, and various other construction hydraulic systems.
Q6: Do these seals prevent "stick-slip" motion?
A: Yes, the PTFE material ensures low friction which effectively eliminates stick-slip behavior during operation.
