The AirTAC Airtac SC40 Standard Cylinder SC40X780S is a genuine double-acting standard air cylinder with a Ø40mm bore and 780mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X780S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 780 mm stroke. It produces a push force of 628 N at 0.5 MPa and reaches 1130 N at the maximum operating pressure of 0.9 MPa, making it a solid mid-range actuator for general automation.
This model includes the -S suffix, indicating a built-in magnet on the piston. This allows standard CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for non-contact position sensing. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, with a total extended body length of approximately 922 mm.

The 780 mm stroke with sensor feedback is ideal for actuating a tall gate or material stop on a conveyor line, providing precise end-of-stroke confirmation to the PLC.
Delivering 628 N at standard line pressure, this cylinder can reliably push parts off a line or transfer them between fixtures in a pick-and-place sequence.
With its built-in magnet for position sensing, the SC40X780S is a dependable choice for long-throw diverter arms in logistics sorting, ensuring packages are routed correctly.
The SC40 bore sits between the smaller SC32 (402 N push) and the larger SC50 (982 N push) at 0.5 MPa. If your application requires more force, stepping up to the 50 mm bore is a direct path; if space or weight is a concern, the 32 mm bore may suffice. For this 780 mm stroke, ensure the load is guided and side forces are managed, as the unsupported 16 mm rod is susceptible to bending under off-axis loads.
To match this cylinder for a replacement, verify five key points: the 40 mm bore, the 780 mm stroke, the PT1/4 port thread, the basic mounting style (no integral bracket), and the presence of the -S magnet for sensor compatibility. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
The theoretical push force is 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is lower due to the rod area, measuring 528 N at 0.5 MPa.
No. The AirTAC SC series is a tie-rod cylinder and has a shorter overall body length than a comparable ISO 15552 profile cylinder. It will only directly replace another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and mounting configuration.
