The function of the non-standard cylinder have?

The function of the non-standard cylinder have? ( 1) Normal cylinder: including cylinder of single and double action. In the case of no special requirements usually use this kind of cylinder. ( 2) Buffer cylinder, cylinder with buffer device, can avoid there was an intense impact piston movement to the end. In high pressure and the working situation of high speed, often use this kind of cylinder. ( 3) The gas - Hydraulic damping cylinder, cylinder and hydraulic cylinder series, can obtain the stable movement speed, can be used for requiring higher speed such cylinder. ( 4) Oscillating cylinder, cylinder reciprocating action as around the axis of rotation, can be used for the fixture transposition, valves, etc. ( 5) Impact cylinder: is a kind of high speed movement form the impact of high-energy cylinder, piston rod can be used for punching, cutting, etc.
