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).
