Description

Piston seal SPGW is a high performance double acting compact piston seal consisting of a PTFE piston-seal friction ring, a profiled pre-loaded NBR elastomer and two POM back up rings. It is suitable for a wide range of PTFE materials, the most common being bronze, MoS2, or carbon are the most commonly used for fluid power service, other high-performance materials are also available to suit your needs. The most commonly used energizer is the NBR Shore 80A.

When used in a variety of fluids and high temperatures, it is suitable for wider piston spacing. By stacking, the SPGW compact seals form a compact structure and excellent performance, mounted in a single piston groove.

Its geometry gives it overall stability, wear resistance, tightness, low friction and long life without maintenance. Due to the initial shrinkage range set, the seal has good sealing properties at low pressure.

When the pressure is raised, the sealing performance remains good because the elastomer exerts a stress on the combined seal ring, thereby converting the axial force from system pressure to radial compression. Suitable for overloaded nylon shielding rings. Designed to protect seals from crushing damage, it meets the requirements of a wide range of hydraulic cylinders.
