- High sliding speed;
- Low friction,free of stick-slip;
- Simple groove design;
- Long service life;
- Very good sealing performance even with pressure peaks;
- High resistance to abrasion;
- Increase clearance possible.
Resistance in oil, abrasion, solvent, weather
Excellent heat resistance, chemical resistance, solvent resistance, fluorination resistance, vacuum resistance, oil resistance, aging resistance and other properties
Reciprocating hydraulic system. In the high-pressure conditions of the bi-directional piston seal reload occasion very well.
Particularly suitable for long stroke and a wider range off luids and high temperature applications, applicable to the larger piston clearance. Mainly used in heavy construction machinery or cylinder piston seal leakage has good control, anti-extrusion
resistance and loss of performance, such as: excavators, and other heavy-duty hydraulic cylinders.
