HBYR type piston rod seal is a high-performance sealing part designed for hydraulic cylinder piston rod applications. Made of premium polyurethane blend material, this rod seal boasts outstanding wear resistance, oil resistance and reliable anti-extrusion property, maintaining stable sealing performance under continuous reciprocating motion and variable hydraulic pressure.
The HBYR piston rod seal features an optimized sealing lip profile. It creates uniform contact pressure on the piston rod surface to effectively block hydraulic fluid leakage, while lowering sliding friction to reduce heat generation and surface abrasion. It can withstand frequent back-and-forth movement and sudden pressure spikes in hydraulic systems. Apart from preventing internal hydraulic oil escape, the seal can also keep external dust, sand and metal particles out of the cylinder, protecting the piston rod from scratches and extending the service life of the whole hydraulic equipment.
Precision manufacturing ensures consistent dimensional accuracy. The HBYR seal fits standard seal grooves, supporting quick installation and convenient spare part replacement. It is widely used in construction machinery, hydraulic presses, forklifts and other industrial hydraulic facilities. Choosing HBYR piston rod seals helps reduce equipment downtime and cut long-term maintenance costs for hydraulic systems.
