The AirTAC Airtac SC40 Standard Cylinder SC40X440S is a genuine double-acting standard air cylinder with a Ø40mm bore and 440mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X440S is a double-acting tie-rod cylinder with a 40 mm bore and a 440 mm stroke, equipped with a built-in magnet for barrel-mounted sensor detection. At the standard operating pressure of 0.5 MPa, this pneumatic actuator generates a push force of 628 N and a pull force of 528 N, providing reliable linear motion for medium-duty automation tasks.
This model features a 16 mm diameter piston rod with an M12x1.25 male thread, a 21 mm adjustable air cushion at each end, and a PT1/4 port. The body length A is 142 mm, giving an approximate extended length of 582 mm. The built-in magnet, designated by the -S suffix, allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel profile for precise, non-contact end-of-stroke sensing.

The 440 mm stroke and magnetic piston sensing make this cylinder ideal for actuating diverter gates on packaging conveyors, providing reliable product sorting with end-of-stroke confirmation to the PLC.
Delivers the consistent 628 N force needed for moving adhesive dispensing heads across a 440 mm path. The built-in magnet allows for multi-position sensing to control bead start and stop points accurately.
Used in light-duty vertical lifts or horizontal transfer stations, the SC40X440S provides a smooth, cushioned motion. The adjustable air cushion decelerates the load quietly at each end of the 440 mm travel.
Select the SC40 bore when your application requires a force output in the 500-600 N range at typical plant pressure. If you need higher force, stepping up to the SC50 bore provides 982 N of push force at the same 0.5 MPa. For a 440 mm stroke, consider the rod bearing support: long strokes with a 16 mm rod can be susceptible to side-load bending. If the load is not guided externally, an external linear guide or a guided cylinder variant is recommended to prevent premature rod bearing and seal wear.
To ensure a correct drop-in replacement, match five key specifications: the 40 mm bore, the 440 mm stroke, the PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This cylinder is a direct replacement for another AirTAC SC40X440S or an equivalent tie-rod cylinder matching these exact parameters.
Quick checklist
At 0.5 MPa, the theoretical push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. For forces at other pressures, multiply the bore area (12.57 cm²) by your pressure in MPa.
Yes. The -S suffix in the model code indicates a built-in magnetic piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's sensor slot to detect piston position without any additional brackets.
