SPGM Compact and Combined Piston Rings

SPGM Compact and Combined Piston Rings



The SPGW profile is a high-performing, double acting compact piston seal composed of a dynamic brone-illed PTFE friction ring, profiled pre-tightened NBR ring and two POM back-up rings. It is characteristic of excellent performances against leakage, extrusion and friction. SPGW combined sealing ring is especially applicable for long journey. When used for the wide range of fluids and at high temperature, it is applicable for wider spacing of piston. By superposing, SPGW combined sealing ring forms a compact structure
and excellent performance, which is installed a single piston groove. Its geometry endows it with overall stability, abrasion resistance, tightness, low friction and long life without maintenance. Because initial shrink range is set, the sealing ring has a good sealing performance under low pressure. When the pressure is raised, the sealing performance keeps stil good because the elastomer stresses on the combined sealing ring, thus convering axial force from the system pressure to the radial extrusion. It is applicable for the overloading nylon shield ring. It is designed specially to protect sealing ring from the damage of extrusion, meeting the requirements of all kinds of hydro-cylinder.

Application and Properties:


Suitable for long stroke, a wide range of fluids and high temperature occasions. The application of heavy duty double acting piston sealing under high pressure conditions is excellent. Applicable to larger piston clearance , it has good leakage control, extrusion resistance and wear resistance in heavy duty and construction machinery cylinder piston sealing system. Good static sealing property, simple groove structure, larger extrusion clearances can be allowed, be able to work in dusty condition.


Working Conditions:


Diameter Range Pressure Range Temperature Range Speed Medium
50 - 350mm 0 - 50MPa -30℃ +100℃ 1.5 m/s hydraulic oil, flame retardant liquid, water and others


Low friction coficient; no stick-slip effect
Possible increase in extrusion gaps
Excellent extrusion resistance even during pressure peaks
Excellent abrasion resistanceAssembled by deformation
