Descripción completa del producto

The single-acting pneumatic complete piston EK is a two-component seal design, consisting of a metallic carrier with a vulcanized guiding surface and sealing lip. The complete piston performs two functions: sealing and guiding.


• 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 end position cushioning, provided that no excessive lateral guidance loads will occur (long strokes and buckling).

The EK complete piston with integrated seals is available in the following compounds:
Z5051 - Industrial applications
