PARKER CR ROD SEAL

    CR Rod Seal

    Descriptions

    The CR double-acting rod sealing set featuring a Caveseal design consists of a PTFE rod sealing ring and an elastomer O-ring as a preloading element. The sealing set is suitable for dynamic applications as an alternative to an O-ring in situations requiring optimum sealing performance and friction. The Caveseal design enables installation in smallest grooves.
    Due to the material combination of the slipper ring (PTFE) and the O-ring (elastomer), this product is suitable for a wide range of applications, especially for aggressive media and/or high temperatures. An extensive selection of materials is available for specific application profiles.

    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.
    • Assembly on one-part piston is possible.
    • High temperature resistance assured by suitable O-ring compound selection.
    • Adaptable to nearly all media thanks to high chemical resistance of the sealing ring and large O-ring compound selection.
    • Short axial assembly length.
    • Short radial assembly depth.
    • Installation in closed and undercut housings.
    • Available in diameters from 4 to 4500 mm.
    • Can be used in existing O-ring grooves.
    • Additional sizes of machined products available on short notice

    Range of application:
    The CR rod sealing set has been designed to replace standard O-rings. For dynamic applications we recommend our OA product series for pneumatic applications and ON or OE for hydraulic applications.
