High-Pressure Bi-Directional Compact Rod Seal

R56


High-Pressure Bi-Directional Compact Rod Seal

Designed with an energizing element for easier fitment and responsiveness to changing pressures. Integrated rod wear rings acting also as back-up rings to eliminate seal extrusion in high pressure systems where positive sealing from both directions is required. Compact and robust design for the most arduous conditions.

*Important Note: Maximum values above depend on extrusion gap, clearances, seal material, media, temperatures, pressures, surface speed, dynamic running surface finish and working environment. Seals cannot be operated at their upper ratings at the same time. Pressure ratings can be increased by reducing clearances.
