The AirTAC Airtac SC40 Standard Cylinder SC40X1380S 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 SC40X1380S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and an extended 1380 mm stroke, built with a tie-rod construction that is shorter than an ISO 15552 profile. At 0.5 MPa it delivers 628 N pushing force and 528 N pulling force, rising to 1130 N push at 0.9 MPa, driven by a 16 mm diameter piston rod with M12x1.25 male threads.
This model carries the -S suffix for a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The 1380 mm stroke exceeds the standard maximum of 1200 mm for bore 40, making this a non-standard made-to-order length. Ports are PT1/4, seals are TPU for a -20 to +70 °C range, and the adjustable air cushion is 21 mm long to decelerate the piston quietly.

The 1380 mm stroke moves components between widely spaced conveyor stations, and the built-in magnet lets sensors confirm full extension and retraction at each cycle.
Delivers a long, straight linear pass for adhesive or sealant beads. The adjustable cushion protects the tooling at stroke ends, while the 16 mm rod resists deflection under light guided loads.
Operates a tall hopper gate or air damper with 528 N of pull force at 0.5 MPa. Sensor feedback from the -S magnet confirms open/closed status for interlock safety logic.
Choose the SC40 when 628 N at 0.5 MPa fits the load; for roughly 50 % more force step up to the SC50 (982 N at 0.5 MPa), and for a lighter compact alternative step down to the SC32 (402 N). At 1380 mm stroke the unsupported rod is subject to bending under side load — always guide the load externally or pair the cylinder with a dedicated guided unit to protect the rod bearing and seal.
For a drop-in replacement match five points: 40 mm bore, 1380 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting. This cylinder fits where an existing AirTAC SC40 of the same configuration was used; it is not dimensionally interchangeable with ISO 15552 cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure it produces 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
It is not recommended. At 1380 mm the 16 mm rod is long relative to its diameter, making it vulnerable to bending and premature bearing wear if side loads are present. Always use an external guide rail or a guided cylinder assembly for long-stroke applications.
