PARKER OG PISTON SEAL

    OG Piston Seal

    Descriptions

    The single-acting piston sealing set profile OG consists of a PTFE piston sealing ring
    and an elastomer O-ring as a preloading element.
    The asymmetrical cross-section of the slipper ring is designed for best drag oil performance during stroke in both directions.
    Profile OG is particularly suitable for single-acting pistons in control cylinders, in servo
    controlled systems, machine tools, quick acting cylinders.
    The material combination of the slipper ring (PTFE) and the O-ring (elastomer) makes
    this product suitable for a wide range of applications, especially for aggressive media
    and/or high temperatures. Multiple compounds can alternatively be selected according to the individual application profile.

    Features

    • Good sealing performance in extremely
    small assembly conditions.
    • Excellent wear resistance.
    • Minimal break-away and dynamic friction and no stick-slip tendency ensures
    uniform motion even at low speeds.
    • Good energy efficiency due to low friction.
    • Insensitive to pressure peaks.
    • High temperature resistance assured by
    suitable O-ring compound selection.
    • High extrusion resistance.
    • Adaptable to nearly all media thanks to
    high chemical resistance of the sealing
    ring and large O-ring compound selection.
    • Dimensions according to ISO 7425-1.
    • Also available as double-acting version.
    • Short axial assembly length.
    • Installation in closed and undercut
    housings.
    • Available in diameters from 4 to
    3000 mm.
    • Additional sizes of machined products
    available on short notice.

    Range of application

    Operating pressure ≤ 400 bar
    in case of reduced extrusion gap (H7/f7) and large cross sections≤ 600 bar
    Operating temperature -30 °C to +100 °C 1)
    Sliding speed ≤ 4 m/s

    1) With deviation from standard temperature range, please contact our consultancy service for adequate O-ring compound.
