PARKER EK PNEUMATIC SEAL

    Pneumatic Seal EK

    Range of application
    Complete piston for single-acting pneumatic cylinders with and without cushioning,provided that no excessive lateral guidance loads will occur (long strokes and buckling).

    • Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
    • Immediate response (full pressure load) thanks to incorporated venting channels.
    • Good wear resistance.
    • Ideal corrosion protection thanks to complete elastomer covering.
    • Smooth running due to optimum lubricant-retaining sealing lip geometry.
    • Easy attachment to the piston rod without additional sealing elements.
    • Easy installation due to integrated static sealing function.
    • Excellent media resistance in case of suitable compound selection.
    • Also available as double-acting version.
    • Low assembly height of the complete piston enables short cylinder designs.
    • Versatile complete piston for nearly all cylinder designs.

    Range of application
    Complete piston for single-acting pneumatic cylinders with and without cushioning,
    provided that no excessive lateral guidance loads will occur (long strokes and buckling).
    Operating pressure≤ 16 bar
    Operating temperature-30 °C to +80 °C
    Sliding speed≤ 1 m/s
    MediaCompressed air, both lubricated and oil
    free (after greasing for fitting)

    Installation
    The profile EK complete piston is fixed to the piston rod with a locknut to avoid loosening. For use with dry and oil-free air, the piston and cylinder tube must be prelubricated with a suitable long-life lubricant.It must be assured that the sealing lips do not touch the cylinder bottom and the cylinder cap at the limit stops (see also dimension „Ø dm“).
