HUNGER GD1000K-S PISTON SEAL

    GD1000K-S PISTON SEAL

    In addition to proven compact piston seal GD1000K and GKD Hunger offers a slim version GD1000K-S which is identical in construction to most of competitors piston seals with integrated bearing elements.
    The seal kit combines a compact sealing and bearing function especially for shorter piston widths and can be used for already existing groove designs. Standard version of GD1000K-S is a double acting, 6 part piston seal consisting of two L-rings, two bearing elements , one elastomer energizer and a PTFE-compound slide ring which can easily be pulled and assembled over the piston.

    Both L-rings protect the slide ring from gap extrusion even at higher pressure grades, the low friction PTFEcompound slide ring enables smooth, stick-slip free piston movement. Listed dimensions are equipped with same wear resistant and reliable standard materials like GD1000K – these can be modified and adapted to all kinds of requirements of the hydraulic cylinder.
