Item Information

The Ultrathan® PP cushioning ring is used for sealing cushioning pistons in pneumatic cylinders in the end position. By means of the sealing lip its special shape provides sealing toward the cushioning piston and concurrently acts as a valve during the return stroke. The combination of geometry and material ensures high wear resistance.

• No mechanical check valves required since their function is performed by the cushioning rings.
• High cushioning consistency due to automatic centering, even in the case of misalignment of the cushioning spear and the cylinder head.
• Optimum use of design-related cushion travel.
• Robust seal profile for harshest operating conditions.
• Immediate response to reversed direction thanks to incorporated venting channels.
• Extreme wear resistance.
• Easier installation.
• Excellent media resistance in case of suitable compound selection.
• Installation in closed housings.

Range of application:
For pneumatic cylinders with end-position cushioning.
