The common compact seal SPGW is made of a sealing ring, an O-ring and back up ring.

Sealing ring material is generally filled with PTFE; the O-ring is made of nitrile rubber (NBR). ) or fluororubber (FKM); the back up ring is made of polyoxymethylene (POM) material. The combined seal SPGW has good dynamic and static sealing performance, low friction coefficient, no creeping at startup, and more importantly, stable operation.

SPGW is a high performance double acting compact piston seal consisting of a dynamic bronze filled PTFEhttp://dshseals.com/piston-seal friction ring, a profiled preloaded NBR ring and two POM back up rings. It has excellent resistance to leakage, extrusion and friction. SPGW compact seal is especially suitable for long-distance travel. 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.

 

Advantages

 

  • Low friction coefficient; no stick-slip effect.

  • Possible increase in extrusion gaps.

  • Excellent extrusion resistance even during pressure peaks.

  • Excellent abrasion resistanceAssembled by deformation.
