UDR type piston rod seal is a high-performance reciprocating sealing element developed for hydraulic cylinder rod applications. Manufactured from high-quality polyurethane and rubber composite materials, this rod seal exhibits excellent wear resistance, oil resistance and tear strength, maintaining consistent sealing performance under continuous dynamic movement and variable pressure conditions.
With a specially optimized sealing lip profile, the UDR piston rod seal creates a tight barrier against hydraulic fluid leakage while reducing contact friction between the seal and rod surface. It can effectively withstand repeated reciprocating motion, resist extrusion and prevent hydraulic oil from escaping outside the cylinder. Meanwhile, it blocks contaminants such as dust, mud and metal particles from invading the internal hydraulic system, protecting the piston rod from scratches and extending the service life of the whole cylinder.
Precision machining ensures strict dimensional accuracy, making the UDR seal easy to install into standard seal grooves. It is widely used in construction machinery, hydraulic presses, forklifts and other industrial hydraulic equipment. Whether for new cylinder assembly or spare part replacement, UDR piston rod seal offers stable sealing reliability and reduces downtime and maintenance costs for hydraulic systems.
