派克PP型緩沖密封-Parker - PP CUSHIONING SEAL

The profile PP pneumatic cushioning seal is specially designed for cushioning spears in pneumatic cylinders.

Main advantages:

·         As the seal functions as a check valve, no separate valve is necessary.

·         Optimum use of design-related cushion travel.

·         High cushioning consistency due to automatic centering, even in the case of misalignment of the cushioning spear to the cylinder head.

·         Increased reliability due to two independent sealing systems (flexible sealing lips and axial sealing areas).

·         Easy manual snap assembly.

·         Suitable for use in lubricated as well as dry and oil-free air (after initial lubrication during assembly).
