More thrust than conventional cylinders by connecting in series 2, 3 or 4 cylinders with the same piston diameter and the same stroke.

Multi stage pneumatic cylinder

Multi stage pneumatic cylinder

Diameter 25, 40, 63, 100 mm

Stroke length 1 ... 2000 mm

By connecting 2 to 5 cylinders in series with the same piston diameter and different stroke lengths, up to 6 positions can be approached.

Selection Guide

Multi stage pneumatic cylinders

Several positions can be reached with a multi stage pneumatic cylinder. A three or four-stage cylinder consists of two separate cylinders with piston rods extending in the opposite direction. Depending on control and stroke distribution, the cylinder can therefore assume up to four positions, each of which is moved exactly to the stop.
To achieve 3 positions, two cylinders of the same stroke length must be connected to each other. With 4 positions, two cylinders of different stroke lengths are connected to each other.
It should be noted that when one end of the piston rod is stationary, the cylinder barrel carries out the movement. The cylinder must be connected with movable pipe connections.
The cylinders are connected with a multi-position kit. Festo offers multi-position kits for the ADN compact air cylinders and DSBC/DSBG profile/tie rod air cylinders as well as DNC.

High-force cylinders

A high-force cylinder is a cylinder design defined by a series of compact pneumatic cylinders. By connecting a maximum of four pistons in series, the force of the cylinder can be multiplied analogously. The resulting force is transmitted to the external piston rods and can be used by the customer from there. The resulting force is applied over the entire stroke – up to a maximum of 5 mm before reaching the end position.
The cylinder of the first stage is always used for position sensing, as it performs the visible stroke.

Tandem cylinders

These are two identical profile barrel cylinders of the DNC type arranged in series for doubling the thrust force in both directions of movement. By using DNC cylinders, the mounting interfaces comply with the ISO 15552 standard. This means that the mounting accessories from the DSBx and DNC piston rod cylinder range can be used as well as the piston rod accessories. Both profile cylinders of the tandem have magnetic pistons and can be sensed by means of proximity sensors. The proximity sensors can be easily and securely mounted in one of the sensor slots without any additional accessories. The energy can be reliably absorbed by the adjustable pneumatic cushioning. DNCT is available with a freely selectable stroke length up to a maximum of 500 mm either in a standard version or in a heat-resistant version up to a maximum ambient temperature of 120 °C.
