The UDR‑Type piston rod seal is a high‑performance dynamic hydraulic sealing component specially designed for reciprocating piston rod applications, widely applied in construction machinery, hydraulic cylinders, material handling equipment and general industrial hydraulic systems. Manufactured from high‑strength polyurethane elastomer, this UDR piston rod seal possesses remarkable wear resistance, extrusion resistance and stable elastic recovery under continuous cyclic pressure.
Optimized lip profile provides well‑distributed contact pressure against the piston rod surface. It effectively inhibits hydraulic medium leakage during frequent extension and retraction movements and reduces stick‑slip for smooth cylinder operation. The seal maintains consistent sealing performance under pressure fluctuations and varying ambient temperatures, showing good compatibility with mineral hydraulic oil and conventional working fluids.
With compact structural design, UDR‑Type piston rod seal perfectly matches standard seal grooves for quick installation without secondary machining. It stands up to harsh working conditions including vibration and heavy‑load impact, slowing down premature seal aging and abrasion. Excellent durability helps lower equipment failure rate, decrease maintenance work and spare‑part replacement costs. Custom sizes and different material options are available to satisfy various rod‑diameter demands for global industrial customers.
