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

• Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
• Cushioning buffers on the piston´s front faces with integrated ventilation ducts provide for mechanical cushioning of the cylinders.
• Multi-functional element: seal, guiding and cushioning element.
• 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 adjustment of the functional lips.
• 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 end cushioning, provided that no excessive lateral guidance loads will occur (long strokes and buckling).

The DE complete piston with integrated seals is available in the following compounds:
Z5117 - Industrial applications
Z5142 - High temperatures
