Hydraulic cylinder piston sealing ringThis 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 ° CLow temperature nitrile rubber: -40~100 ° CMaterial: PTFE+rubberSpeed: max=1.5m/sMaximum 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 seali&…
