PARKER OR ROTARY SEAL

    OR Rotary Seal

    Descriptions

    Producers of rotary distributors prefer simplified seal designs. This can be achieved
    by means of profile OR internally sealing rotary sealing sets.
    The OR sealing set consists of a wear-resistant, low-friction slipper sealing ring and
    an elastomer O-ring as a preloading element.
    It is suitable mainly for applications where the pressure alternates from one side of the
    seal to the other, such as pivots for rotating track rings, swivel joints, hose reels, and
    in machine tool hydraulics. If the sealing set is used as an end seal, it is recommended
    to install a wiper ring at the end of the components.
    Depending on the special working conditions, the rotary sealing set OR is equipped
    with one or two circumferential lubricating grooves.

    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.
    • Improved lubrication due to pressure
    medium deposit in the dynamic contact area.
    • High extrusion resistance.
    • Adaptable to nearly all media thanks to
    high chemical resistance of the sealing
    ring and large O-ring compound selection.
    • 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 ≤ 300 bar
    Operating temperature -30 °C to +100 °C 1)
    Sliding speed ≤ 1 m/s

    Recommendation for rotary transmissions: P × v ≤ 25 (40)
    (For definition see catalogue „Hydraulic Seals“, chapter „Rotary Seals“, introduction.)

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

    Compounds
    Sealing ring: Polon® 033, modified PTFE + 25 % carbon.
    O-ring: N0674, NBR elastomer with approx. 70 Shore A.
    Installation
    For diameters < 30 mm open grooves are required.
    This seal should only be used in combination with closed guiding elements.
