PARKER ZW PISTON SEAL

    ZW Piston Seal

    Descriptions

    The profile ZW double-acting piston sealing set consists of an elastomer sealing component, two anti-extrusion and two angular guide rings.

    Features

    • Good wear resistance.
    • Assembly on one-part piston is possible.
    • Installation in closed and undercut
    housings.

    Range of application
    Sealing set for double-acting pistons in presses, drive cylinders, back-up and operating cylinders for industrial and mobile hydraulics.

    Operating pressure ≤ 400 bar
    Operating temperature -35 °C to +100 °C
    in HFA, HFB and HFC fluids +60 °C
    Sliding speed ≤ 0.5 m/s

    Compounds
    Rubber component: Highly wear-resistant NBR-compound NB078 with a hardness
    of 80 Shore A.
    Anti-extrusion rings: High-strength, wear-optimized polyester elastomer (W5035).
    Angular guide rings: Thermoplast for high pressure resistance even with increased
    temperatures (W5301).
    Installation
    Sharp edges and burrs in the assembly area of the seal must be removed. Assembly is
    performed in the following sequence: „rubber seal, anti-extrusion rings, angular guide
    rings“. Ensure that the contact points (gaps) of the angular guide and anti-extrusion
    rings are arranged in staggering positions.
