The AirTAC Airtac SC40 Standard Cylinder SC40X40STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 40mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X40STC is a double-acting tie-rod cylinder with a 40mm bore and 40mm stroke, factory-equipped with a built-in magnet and centre trunnion mount. It produces a push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, driven by a 16 mm diameter piston rod.
This model includes the -S magnet option for direct mounting of CMSG/DMSG/EMSG sensors and the TC centre trunnion bracket (F-SC40TC, supplied with TCM1) for pivoting motion. The compact 40 mm stroke suits short-throw clamping, ejecting, or diverting tasks where the cylinder body must swing.

Actuating a pivoting diverter gate on a compact conveyor line, using the TC trunnion to allow the cylinder body to swing freely.
Operating a short-throw clamp on a machining fixture, with the magnet confirming full retraction via a CMSG sensor.
Providing the ejection stroke on a small assembly station, where the trunnion mount simplifies alignment in a tight space.
The SC40X40STC is ideal for short-stroke pivoting applications. If higher force is needed, stepping up to the 50 mm bore provides 982 N at 0.5 MPa. For longer strokes, ensure the rod is not subjected to side load, as the 16 mm rod may bend under misalignment. When replacing, match bore, stroke, PT port thread, the TC centre trunnion mount, and the -S magnet sensor compatibility.
Quick checklist
At 0.5 MPa it delivers 628 N extending and 528 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force rises to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, PT port, TC mount, and magnet option.
