Rod seals are vital components in hydraulic sealing systems, ensuring the prevention of hydraulic fluid leakage. Positioned between the cylinder head and piston rod, their function is to maintain a continuous sealing contact during the rod's sliding motion. For heavy-duty applications, a combination of rod and buffer seals is typically used to enhance sealing performance and durability. Rod seals also retain a thin lubrication film on the piston rod, essential for lubrication and corrosion prevention.
HydraPak’s rod seals are available in single acting (pressure from one side) and double acting (pressure from both sides) profiles in a wide variety of operating conditions. Their design ensures that pressurized fluid remains within the system, preventing leaks that could degrade equipment performance and cause environmental harm. Selecting the appropriate rod seal involves considering cylinder design, system pressure, temperature, and other application criteria, with options available in various profiles and materials. A meticulous selection process of the rod seal ensures optimal sealing performance and extends the service life of hydraulic systems.
