The UDI‑Type piston rod seal is a high‑performance dynamic sealing element developed for hydraulic cylinder piston rod reciprocating motion, widely used in engineering machinery, material‑handling devices, agricultural machinery and various general industrial hydraulic systems. Made of premium polyurethane elastomer material, the UDI piston rod seal delivers outstanding wear resistance, anti‑extrusion property and durable elastic resilience under variable pressure loads.
Its precision‑optimized sealing lip creates even contact pressure on the rod surface. It reliably blocks hydraulic oil leakage during repeated extension and retraction cycles and effectively minimizes stick‑slip phenomenon to guarantee stable and smooth cylinder movement. This rod seal keeps consistent sealing performance within wide pressure and temperature ranges, and holds great compatibility with mineral hydraulic oil and most common industrial hydraulic media.
Compact structure fits standard seal grooves perfectly, supporting easy installation with no extra machining required. It performs excellently under tough working surroundings with vibration and cyclic impact loads, slowing abrasive wear and delaying seal aging. Long‑term reliable sealing reduces hydraulic system failure risks, cuts equipment downtime and lowers overall maintenance and replacement costs. Custom sizes and alternative material grades can be provided to meet diverse specification requirements for global industrial purchasers.
