SE(M)

These cylinders are supplied with compressed air on one side only for actuation. A spring returns the unloaded cylinder with low force — out (e.g. SE series, normally in) or in (e.g. SES series, normally out). These two versions are also commonly referred to as a push cylinder (SE series) or a pull cylinder (SES series). A spring resets the cylinder to its initial position.

Short strokes and immediate response

If, for safety reasons, an immediate return from the working position is required in the event of an interruption of the compressed air supply, these cylinders are of fundamental importance. In such cases, the spring or the push force brings the piston rod back to its rest position. You will encounter these cylinders in applications where short strokes and immediate response are required. The spring inside the cylinder chamber is dimensioned in such a way that tension remains low, thereby preventing unnecessary energy losses.
