The PSD piston rod seal is a professional sealing component specially developed for hydraulic cylinder piston rods. Its core task is to prevent hydraulic medium leakage outward along the reciprocating rod and stop external dust, dirt and particles from invading the hydraulic cylinder interior.
Produced from high-performance polyurethane material, the PSD rod seal boasts excellent tear resistance, low friction coefficient and strong anti-extrusion capability. The precisely optimized sealing lip maintains even contact pressure against the rod surface. It keeps consistent sealing performance under fluctuating working pressure and repeated reciprocating motion, reducing friction heat and slowing down wear during long-time cyclic operation.
This PSD piston rod seal supports a broad working temperature and pressure range, and features great compatibility with most conventional hydraulic oils. It runs stably under heavy loads and tough operating conditions, offering reliable protection against abrasion and extrusion failure.
It is widely adopted in construction machinery, forklifts, hydraulic presses, mining equipment and various industrial hydraulic cylinders. Simple installation helps improve assembly efficiency. With long service life, it effectively minimizes oil leakage and lowers equipment maintenance and replacement expenses.
