The MYR piston rod seal acts as a critical buffer seal in hydraulic cylinder assemblies, engineered to safeguard the main sealing elements against sudden pressure surges in reciprocating hydraulic systems. Constructed from durable polyurethane paired with a rigid POM back-up ring, this MYR rod seal adopts a special pressure release design to drain trapped residual pressure between the buffer seal and primary seal. This function effectively prevents pressure buildup, which is the leading cause of early seal failure under cyclic working conditions.
Boasting excellent wear resistance, low compression set and strong anti-extrusion capability, the MYR piston rod seal retains stable sealing integrity under continuous dynamic operation. It delivers low friction performance to reduce rod wear and oil leakage, compatible with most standard hydraulic fluids and a broad operating temperature range. The standardized groove design allows straightforward installation and replacement, fitting common metric piston rod sizes without extra machining on hydraulic cylinders.
Widely deployed on construction machinery, mining hydraulic equipment, hydraulic presses and material handling cylinders, MYR buffer seals greatly cut equipment downtime and maintenance expenses. By absorbing impact pressure and blocking abrasive contaminants, it prolongs the lifespan of the whole sealing kit. For OEM cylinder manufacturing or aftermarket seal replacement, the MYR piston rod seal remains a cost-effective and trustworthy sealing choice for your heavy-duty hydraulic systems.
