The AirTAC Airtac SC40 Standard Cylinder SC40X75STCN is a genuine double-acting standard air cylinder with a Ø40mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X75STCN is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa, ideal for medium-duty clamping and transfer tasks. Its 75 mm stroke is a standard length within the 40 mm bore range, which supports strokes up to 1200 mm.
This model features a built-in magnet for barrel-mounted sensors, a centre trunnion mount (F-SC40TC) with bracket for pivoting actuation, and NBR seals. The 16 mm diameter piston rod and PT1/4 ports provide a robust connection for reliable cycling in industrial automation.

The 75 mm stroke and pivoting trunnion mount make this cylinder suitable for actuating gates or diverters on conveyor lines, where the magnet confirms position at each cycle end.
With 628 N of push force, it securely clamps components in machining or welding jigs. The NBR seals offer good wear resistance in standard factory air conditions.
The centre trunnion mount allows the cylinder to pivot, making it perfect for driving linkages in packaging or assembly machines where the rod end follows an arc.
Choose the SC40 bore for applications needing up to 628 N at 0.5 MPa. If your force requirement exceeds 900 N, step up to the SC50 bore, which provides 982 N at the same pressure. For lighter, more compact designs, the SC32 bore offers 402 N.
To ensure a drop-in replacement, match five key points: 40 mm bore, 75 mm stroke, PT port thread, centre trunnion (TC) mounting, and the integrated magnet (-S) for sensor compatibility. Always verify the F-SC40TC trunnion bracket dimensions against your existing setup.
Quick checklist
At the standard operating pressure of 0.5 MPa, this 40 mm bore cylinder generates 628 N of force when extending and 528 N when retracting. The maximum force at 0.9 MPa is 1130 N.
It is a direct replacement for another AirTAC SC40 tie-rod cylinder with a 75 mm stroke, PT ports, centre trunnion mount, and a magnetic piston. Always confirm the mounting bracket (F-SC40TC) and port sizes match, as this is not an ISO 15552 profile cylinder.
