Description
Structural Design:
The SPGW double-acting compact piston seal has a robust design which contains an elastomer energizer, a PTFE ring and two thermoplastic back-up rings. Or an elastic energy enhancer, a composite carbon fiber ring, and two carbon fiber support rings.
Excellent performance in hydraulic systems and reciprocating motion applications.
Suitable for both long and short strokes, and can adapt to larger piston clearances in situations involving various fluids and high temperatures.
The design has been a preferred design for a wide range of mobile hydraulic applications with low friction, low extrusion and long service-life properties.
Summary of Advantages:
- Best combination for load holding and low friction sealing
- Design operating at variable pressures
- High extrusion resistance
- Good wear resistance
- Long service life
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
