GSJ step seals are widely used in hydraulic cylinder rod sealing systems. They are designed to provide reliable sealing performance under high pressure, low friction operation, and long service life requirements.
When selecting a GSJ step seal, factors such as groove dimensions, operating pressure, temperature range, media compatibility, speed, and installation direction should be carefully evaluated to ensure optimal sealing performance.
