The AirTAC Airtac SC40 Standard Cylinder SC40X229S is a genuine double-acting standard air cylinder with a Ø40mm bore and 229mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X229S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 229 mm stroke and a factory-installed magnet for sensor compatibility. At the standard operating pressure of 0.5 MPa, it generates a push force of 628 N and a pull force of 528 N, making it a capable mid-range actuator for automated equipment.
This model features a 16 mm diameter piston rod with an M12x1.25 male thread and PT1/4 ports. The adjustable air cushion at each end provides a 21 mm deceleration zone, effectively reducing end-of-stroke impact. The built-in magnet, designated by the 'S' suffix, allows CMSG, DMSG, or EMSG solid-state and reed sensors to be mounted directly onto the barrel for precise, non-contact position sensing.

Operates diverter gates or stops on conveyor lines, where the 628 N push force at 0.5 MPa reliably directs packages or components. The built-in magnet enables end-of-stroke confirmation sensors.
Provides consistent clamping force for machining or assembly fixtures. The adjustable cushion allows for rapid cycling with minimal vibration, and the sensor magnet confirms the clamp is fully engaged.
Suited for test and measurement equipment where a clean, oil-free air supply is used. The TPU seals offer good wear resistance, and the magnetic piston allows for multi-position feedback in automated sample handling.
For applications requiring slightly less force, the 32 mm bore SC32 series provides 402 N of push force at 0.5 MPa, while stepping up to the 50 mm bore SC50 series increases available push force to 982 N. This cylinder is a standard stroke model, well within the 1200 mm maximum for the 40 mm bore.
To ensure a successful replacement, match five key points: the 40 mm bore, the 229 mm stroke, the PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting configuration. The 229 mm stroke combined with the 16 mm rod is generally rigid for axial loads, but any significant side loading requires an external guide system to prevent rod bending and premature seal wear.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder provides a theoretical push force of 628 N and a pull force of 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes. The 'S' suffix in the model code SC40X229S indicates a built-in magnet in the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's tie-rod slots to detect piston position without any additional brackets.
