The AirTAC Airtac SC32 Standard Cylinder SC32X440S is a genuine double-acting standard air cylinder with a Ø32mm bore and 440mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X440S is a double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). With a 12 mm diameter piston rod and a 21 mm air cushion at each end, it provides smooth deceleration even in rapid cycling applications.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG solid-state and reed sensors to be mounted directly on the barrel for reliable, non-contact position sensing. The 440 mm stroke is well within the 1000 mm maximum standard stroke for the 32 mm bore, making it a standard catalog item.

The 440 mm stroke and integrated magnet for position sensing make this cylinder suitable for diverting or sorting small components on a conveyor line, confirming full extension and retraction at each cycle.
Provides a reliable push or clamping action in light assembly fixtures. The sensor magnet allows the control system to verify the cylinder's position before initiating the next step in an automated sequence.
Used in laboratory automation or test rigs where a consistent, repeatable linear force is needed over a specific distance, with sensor feedback for data logging or cycle counting.
The SC32X440S is ideal for light to medium-duty applications. If your force requirement is higher, stepping up to the SC40 bore provides 628 N of push force at the same 0.5 MPa pressure. For strokes over 300 mm with a 12 mm rod, ensure the load is guided externally or supported to prevent rod buckling and bearing side-load wear, especially if the cylinder is mounted horizontally. For a direct replacement, match the 32 mm bore, 440 mm stroke, PT port thread, and ensure the replacement cylinder has the -S magnet option for sensor compatibility.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder provides 402 N of force when extending and 345 N when retracting. The maximum force at the 0.9 MPa operating limit is 724 N extending.
Yes. The 'S' in the model code SC32X440S indicates a built-in magnetic piston ring. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors to the barrel's tie-rod slots to detect piston position without any additional brackets.
