Item Information

The V6 cushioning ring is used for sealing cushioning pistons in pneumatic cyclinders in the end position. The compact seal provides sealing toward the cushioning piston and concurrently acts as a valve during the return stroke. Due to the combination of geometry and material, small grooves are possible.

• No mechanical check valves required since their function is performed by the cushioning rings.
• Optimum use of design-related cushion travel.
• Good wear resistance.
• Easier installation.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Immediate response to reversed direction thanks to incorporated venting channels.
• Short axial assembly length.
• Short radial assembly depth.
• Installation in closed and undercut housings.

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