SPGA Piston Seal – Double-acting bidirectional piston seal with O-ring energizer and integrated wear-resistant guidance ring. Advanced sealing system combines an O-ring actuated sealing element with a robust bearing ring for radial support and anti-extrusion protection. Symmetrical lip profile ensures positive bidirectional sealing while the guidance element absorbs side loads and reduces metal-to-metal contact. O-ring provides uniform preload and compensates for wear, thermal expansion, and pressure cycling. Integrated design simplifies assembly and reduces component count. Ideal for heavy-duty hydraulic cylinders, construction equipment, and high-cycle industrial applications. Material: high-grade polyurethane seal with NBR/FKM O-ring and reinforced polymer guidance ring. Temp: –35°C to +115°C. Pressure: up to 45 MPa. Speed: up to 3.5 m/s.
