UDI type piston rod seal is a high-performance sealing component specially designed for hydraulic cylinder piston rods. Made of high-grade polyurethane and rubber blend materials, this rod seal features excellent wear resistance, oil resistance and anti-extrusion capability, delivering stable sealing performance under continuous reciprocating motion and fluctuating working pressure.
The UDI piston rod seal adopts a well-engineered sealing lip structure. It maintains a proper contact pressure on the rod surface to effectively stop hydraulic oil leakage, while reducing friction to lower heat buildup and component wear. It can withstand frequent linear movement and resist damage from pressure spikes. Besides preventing internal fluid escape, the seal also blocks external dust, sand and metal debris from entering the cylinder, protecting the piston rod from scratches and extending the service life of the whole hydraulic system.
Strict precision manufacturing ensures consistent dimensional accuracy. The UDI seal fits standard seal grooves for quick and convenient installation and replacement. It is widely applied in construction machinery, hydraulic presses, forklifts and other industrial hydraulic equipment. Adopting the UDI piston rod seal helps reduce equipment downtime and cut maintenance costs for hydraulic systems.
