The UN oil seal series is a proven sealing solution for hydraulic cylinders, specifically engineered to withstand dynamic rod motion and internal pressure. Manufactured by NQKSF, the UN series includes three configurations—UN, UNS, and UHS—each suitable for different mounting and performance conditions.
Product OverviewUN: The standard rod seal with a balanced U-cup design, commonly used in industrial hydraulic systems.
UNS: A short-bodied variation for applications with limited axial installation space.
UHS: A heavy-duty version with a longer body, designed to handle higher pressures and more demanding mechanical conditions.
These seals are primarily made from polyurethane (PU), offering excellent abrasion resistance, sealing performance, and durability in both low and high-pressure environments. Depending on operating conditions, NBR and PTFE materials are also available.
