Basic structure of QDC cylinder

The width of the piston is determined by the size of the seal ring and the necessary length of the sliding part. If the sliding part is too short, it is easy to cause early wear and seizure. The material of piston is usually aluminum alloy and cast iron. The piston of small cylinder is made of brass.

Piston rod is an important part of QDC cylinder. High carbon steel is usually used with hard chromium plating on the surface, or stainless steel is used to prevent corrosion and improve the wear resistance of the sealing ring. It can store energy and make use of the compressibility of air. Centralized gas supply can release energy in a short time to achieve high speed response in intermittent motion and buffer. Strong adaptability to impact load and overload. Under certain conditions, the pneumatic device can keep itself.
