Excavator cylinder piston seals SPGO-Green

This type of seal produces low friction and high strength.  The corners are designed with chamfers to resist cold flow. Molded from polytetrafluoroethylene based material,  containing 40% bronze, and machined to strict tolerances. NBR-30~100 ° CFKM-20~160 ° C Low temperature nitrile rubber: -40~100 ° C Material: PTFE+rubber Speed: max=1.5m/s Maximum pressure: Max=35mpa The cylinder piston seal of the SPGO model is a common seal,  Excavator cylinder seal spgo Design description: SPGO SPO is a low-friction piston seal that is dualphase and is equipped with an O-ring for elastic compensation. Suitable for high pressure and low pressure sealing systems. Excavator cylinder oil seals uses a radial interference fit to compress the O-rings to ensure a good seal even at low pressures.  When the system pressure rises, the O- ring exerts a greater force through the fluid,bringing the seal ring against the se…
