The JA rod seal is a compact seal with an anti-extrusion ring. This combination is characterized by smooth running properties, excellent sealing performance and high wear resistance even in harsh operating conditions. Due to its radial preloading, the sealing lip reliably wipes off the liquid film even in low-pressure conditions or non-pressurized movement of the rod. The asymmetric cross-section of the seal has been designed for optimum drag oil return feed during the stroke in both directions. Optimum sealing performance is achieved by installation in a tandem arrangement in combination with a double wiper ring. As an FKM version the JA rod seal can be used a high-temperature variant for TPU buffer seals.
