PARKER R3 ROD SEAL

    R3 Rod Seal

    Descriptions

    The profile R3 rod seal is a sealing element of compact design with a special antiextrusion ring.
    The main advantages of this combination are smooth running, excellent sealing performance and high wear resistance, even under exceptionally hard working conditions.
    These rod seals guarantee a leakfree performance even at low pressures or when rod
    movement occurs without pressure.

    Features

    • Enhanced sealing performance in nonpressurized conditions.
    • Good wear resistance.
    • Insensitive to pressure peaks.
    • High temperature resistance in case of
    suitable compound selection.
    • Improved lubrication due to pressure
    medium deposit in the dynamic contact
    area.
    • High extrusion resistance.
    • Excellent media resistance in case of
    suitable compound selection.
    • Suitable compounds available for
    special requirements of the chemical
    process industry.
    • Suitable compounds available for special requirements of the food processing
    industry.
    • Dimensions according to ISO 5597.
    • Installation in closed and undercut
    housings.

    Range of application
    Seals for piston rods in hydraulic cylinders.

    Operating pressure ≤ 315 bar
    Operating temperature -30 °C to +100 °C
    Sliding speed ≤ 0.5 m/s

    Compounds
    Rubber part:
    Standard: N3544, NBR compound (≈ 88 Shore A).
    For high temperatures: V3664, FKM compound (≈ 85 Shore A).
    Glide ring: Polon
    ® 062, modified PTFE + 60 % bronze.
    Installation
    This rod seal profile R3 is manufactured with a slightly oversized outer diameter, thus
    ensuring a tight fit in the groove. The preload at the inner diameter necessary for the
    functioning of the seal will only be generated after installation.
    The working life of the seal is mainly influenced by the max. gap at the pressureopposite of the sealing element.
