The AirTAC Airtac SC40 Standard Cylinder SC40X200SN is a genuine double-acting standard air cylinder with a Ø40mm bore and 200mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X200SN is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 200 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore, making it a standard, readily available configuration.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The NBR seal (-N suffix) provides reliable sealing for general industrial air service, while the 16 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth end-of-stroke deceleration.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Actuates diverter gates and stops on light to medium-duty conveyor lines, with sensor confirmation of open/closed position via the built-in magnet.
Provides consistent 628 N clamping force for assembly jigs and welding fixtures, with NBR seals suited for workshop air supplies.
Drives pusher arms and carton folding mechanisms in packaging equipment, where the 200 mm stroke handles standard case sizes.
For applications needing more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If space is constrained, the 32 mm bore SC32 series offers 402 N at the same pressure. The SC40X200SN uses standard PT1/4 ports.
When replacing an existing cylinder, match five key points: 40 mm bore, 200 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 at 1.0 MPa is 128 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet is installed in the piston. This allows AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the cylinder barrel's sensor groove for end-of-stroke detection.
