The AirTAC Airtac SC40 Standard Cylinder SC40X1100S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1100mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1100S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa, scaling up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and a 16 mm diameter piston rod, this model is engineered for linear applications requiring a substantial 1100 mm stroke within the standard range for this bore size.
This unit includes a factory-installed magnetic piston, identified by the 'S' suffix, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise position feedback. The total extended body length is approximately 1242 mm, and it features an adjustable pneumatic cushion to decelerate the load smoothly at the end of travel.

Pushing or diverting boxes and packages on a conveyor line where a long 1100 mm reach is needed to clear the main belt width.
Actuating a long-stroke pick-and-place arm in a machine cell, using the magnetic piston to confirm end-of-stroke positions.
Operating a high-lift industrial door or gate, leveraging the 1130 N maximum force for reliable movement.
For applications needing slightly less force, consider stepping down to the 32 mm bore (402 N at 0.5 MPa). If your load requires a higher force margin, the 50 mm bore provides 982 N at the same pressure. When replacing an existing cylinder, ensure a 5-point match: 40 mm bore, 1100 mm stroke, PT1/4 port thread, the basic mounting configuration, and the integrated magnet option.
With a stroke of 1100 mm, the 16 mm rod is susceptible to bending under side loads. To prevent premature bearing wear and rod deflection, it is critical to guide the load externally with a linear rail or use a guided cylinder if side forces are present.
Quick checklist
At the standard operating pressure of 0.5 MPa, this cylinder provides 628 N pushing force and 528 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1130 N.
Yes. The 'S' suffix in the model code SC40X1100S signifies a built-in magnetic piston. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's external groove to detect piston position without additional brackets.
