The AirTAC Airtac SC40 Standard Cylinder SC40X1800 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1800 is a double-acting tie-rod cylinder with a 40 mm bore and an extended 1800 mm stroke, built to order beyond the standard 1200 mm maximum. It delivers a push force of 628 N at 0.5 MPa and 1130 N at the 0.9 MPa maximum operating pressure, driven by a 16 mm diameter piston rod with an M12x1.25 rod thread.
This model features a 21 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 142 mm, giving a total extended length of approximately 1942 mm. PT1/4 port threads and standard TPU seals with a -20 to +70 °C temperature range are fitted as standard.

Pushes or pulls light components across an 1800 mm span on a conveyor line, ideal for diverting or staging parts where a compact cylinder body is needed.
Operates a spray nozzle or dispensing head across a wide work envelope, providing consistent 628 N force for even coverage on large panels.
Mounted vertically to push lightweight items from a deep storage bin, using the full 1800 mm stroke to ensure complete ejection of the contents.
For a 40 mm bore, this cylinder provides 628 N of push force at 0.5 MPa. If your load requires more force, stepping up to the 50 mm bore (SC50) provides 982 N at the same pressure. For a lighter, more compact solution, the 32 mm bore (SC32) offers 402 N.
At 1800 mm, this stroke significantly exceeds the standard limit. Long, unsupported strokes are highly susceptible to rod bending and bearing wear under side loads. For this application, an external guide rail or a guided cylinder is strongly recommended to absorb transverse forces and protect the rod bearings. When replacing this unit, match the 40 mm bore, 1800 mm stroke, PT1/4 port thread, basic mounting configuration, and the absence of a magnet to ensure a correct fit.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force output by the 40 mm bore is 879 N. The pull force on the retract stroke is lower due to the 16 mm rod area, providing 528 N at 0.5 MPa.
It is not recommended. A stroke of 1800 mm on a 16 mm rod creates a high risk of bending, buckling, and accelerated seal wear if any side load is present. An external guide or a guided cylinder must be used to ensure reliable operation and service life.
