The AirTAC Airtac SC40 Standard Cylinder SC40X1230 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1230mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1230 is a double-acting tie-rod cylinder with a 40 mm bore and an extended 1230 mm stroke, exceeding the standard 1200 mm maximum for this bore size. It generates a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa, making it suitable for long-reach material transfer or actuation tasks.
This model features a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston at end-of-stroke, while the TPU seals provide a standard operating temperature range of -20 to +70 °C. Total extended body length is approximately 1372 mm.

Moves components across wide conveyor gaps in packaging lines, using the 1230 mm stroke to bridge distant pick-and-place positions.
Operates remote clamps or gates in assembly jigs where the cylinder must be mounted far from the work point due to space constraints.
Adjusts large air-handling dampers in agricultural buildings, providing the long linear travel needed for full open-to-close modulation.
Choose the SC40 bore for applications needing around 628 N of force at 0.5 MPa. If your load requires more thrust, step up to the SC50 bore which provides 982 N at the same pressure. For strokes beyond 1200 mm, this non-standard model is made-to-order.
At 1230 mm stroke, the 16 mm rod is susceptible to bending under side loads. Use an external linear guide or rod support to prevent bearing damage. For replacement, match bore (40 mm), stroke (1230 mm), PT1/4 port thread, basic mounting, and ensure the magnet option matches your sensor requirements.
Quick checklist
At 0.5 MPa air pressure, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No. The maximum standard stroke for a 40 mm bore SC cylinder is 1200 mm. The 1230 mm stroke is a non-standard, made-to-order length, so lead time may be longer than a standard model.
