DP U-Cup
DP (Complete Pneumatic Piston)
Complete pneumatic piston with mechanical cushioning function, double-acting. The double-acting profile DP is a complete pneumatic piston with a double cup seal and a vulcanized metal disc support. It performs three functions; Sealing, guiding and 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 elemtents.
-
Easy installation due to integrated static sealing function.
-
Excellent media resistance in case of suitable compound selection.
-
Low assembly height of the complete piston enables short cylinder designs.
-
Versatile complete piston for nearly all cylinder designs.
Application:
Complete piston with end cushioning for double-acting pneumatic cylinders, provided that no excessive lateral guidance loads will occur (long strokes and buckling).
