Special Seal For SPGO Piston Seal

Hydraulic cylinder piston seal for excavatorSPGO sealing is applied to piston bidirectional sealing, with high and low temperature resistance, strong extrusion resistance, and extremely low friction coefficient. It can be applied to high-speed motion oil cylinders with small installation grooves and is widely used in engineering machinery. The main disadvantage is that special tooling is required during installation, resulting in a large amount of static leakage.     Hydraulic cylinder piston seal Excavator cylinder oil seals   Excavator Cylinder Piston Seals   Piston seal SPGO Product parameter details D H9 d h9 L+0.2   D H9 d h9 L+0.2   D H9 d h9 L+0.2 70.0  54.5  6.3   100.0  84.0  8.1   130.0  109.0  8.1 75.0  59.5  6.3   105.0  89.5  6.3   135.0  114.0  8.1 80.0  64.5  6.3   105.0  84.0  8.1   140.0  119.0  8.1 8…
