The AirTAC Airtac SC40 Standard Cylinder SC40X700 is a genuine double-acting standard air cylinder with a Ø40mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X700 is a double-acting tie-rod cylinder delivering a push force of 628 N at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and a 700 mm stroke, it suits mid-length linear actuation tasks where consistent pneumatic force is needed.
This model features a 16 mm diameter piston rod with M12x1.25 threads and a 21 mm adjustable air cushion at each end. The body length A is 142 mm, giving a total extended length of approximately 842 mm. It uses PT1/4 ports and operates on filtered air from 0.15 to 1.0 MPa.

Actuates diverter gates on conveyor lines, using the 700 mm stroke to sweep parts between lanes with reliable force at standard shop air pressure.
Provides the long, steady travel needed to move a dispensing head across a panel or workpiece, with adjustable cushioning for smooth stops at each end.
Extends to fold large carton flaps in packaging machinery, where the 628 N push force at 0.5 MPa is sufficient to crease and hold cardboard during the cycle.
For applications needing more force, step up to the SC50 bore which provides 982 N of push force at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the SC32 bore offers 402 N at the same pressure. At a 700 mm stroke, ensure the rod is protected from side loads; an external guide or self-guided tooling is recommended to prevent rod bending and premature bearing wear.
To replace an existing cylinder, match five key points: 40 mm bore, 700 mm stroke, PT1/4 port thread, basic mounting (no brackets), and no magnet. This ensures a direct dimensional and performance swap for another AirTAC SC40 cylinder.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace it only with another AirTAC SC40 tie-rod cylinder matching the same bore, stroke, port, and mounting.
