The AirTAC Airtac SC40 Standard Cylinder SC40X1380 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1380mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1380 is a double-acting tie-rod cylinder with a 40 mm bore and an extended 1380 mm stroke, suitable for long-reach linear actuation where standard strokes are insufficient. At 0.5 MPa it delivers 628 N pushing force and 528 N pulling force, and the 16 mm diameter piston rod with M12x1.25 male thread provides a robust connection for tooling.
This non-standard stroke model uses the SC body length A of 142 mm, resulting in a total extended length of approximately 1522 mm. The PT1/4 port and adjustable pneumatic cushion with a 21 mm cushion length help decelerate the piston smoothly at end-of-travel, protecting the end caps during high-cycle operation.

The 1380 mm stroke moves pallets or boxes across wide conveyor transfer stations, using the 628 N push force at 0.5 MPa to handle moderate payloads.
Raises and lowers access panels or machine guards over a long travel distance, with the adjustable cushion softening the stop at both ends of the 1380 mm cycle.
Positions a clamping arm deep inside a welding or assembly fixture, where the slim tie-rod body fits into confined spaces along the 1380 mm working envelope.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N push at 0.5 MPa, while a step down to the 32 mm bore SC32 series offers 402 N. This 1380 mm stroke exceeds the 1200 mm maximum standard stroke for 40 mm bore, making it a made-to-order item. When specifying a replacement, match the 40 mm bore, 1380 mm stroke, PT1/4 port thread, basic mounting, and absence of a magnet.
At this stroke length, the 16 mm rod is susceptible to bending under side load. External linear guides or a guided cylinder configuration are strongly recommended to protect the rod bearing and seal from premature wear.
Quick checklist
At the standard operating pressure of 0.5 MPa, the pushing force is 628 N and the pulling force is 528 N. At the maximum operating pressure of 0.9 MPa, the pushing force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No, the maximum standard stroke for a 40 mm bore SC cylinder is 1200 mm. The 1380 mm stroke is a non-standard, made-to-order length. For strokes this long, an external guide mechanism is recommended to prevent rod deflection and ensure reliable sealing.
