SPGO Piston Seal – O-Ring Energized Bidirectional Piston Seal for Double-Acting Hydraulic Cylinders.
SPGO O-ring energized bidirectional piston seal for double-acting hydraulic cylinders. Wear-compensating, pressure-responsive, low friction. PU + NBR/FKM, –35°C~110°C, ≤40 MPa.
SPGO Piston Seal – A premium O-ring energized bidirectional piston seal engineered for double-acting hydraulic cylinders requiring reliable sealing and wear compensation. This hydraulic piston seal features an O-ring actuator that provides uniform radial loading to the sealing lip, ensuring consistent sealing performance across varying pressures and temperatures. The symmetrical lip configuration delivers reliable bidirectional sealing with excellent pressure response, while the O-ring energizer compensates for wear, thermal cycling, and system pressure fluctuations, extending seal service life. The optimized groove design simplifies installation and prevents seal twisting, making this double-acting piston seal ideal for medium to high-pressure cylinders in mobile equipment, industrial machinery, and actuator applications. Material: high-grade polyurethane sealing element with NBR/FKM O-ring. Temp: –35°C to +110°C. Pressure: up to 40 MPa. Speed: up to 3 m/s.
