The AirTAC Airtac SC40 Standard Cylinder SC40X800SFA is a genuine double-acting standard air cylinder with a Ø40mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X800SFA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With an 800 mm stroke and a 16 mm diameter piston rod, it suits medium-reach linear tasks where sensor feedback is required.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel. The FA front rectangular flange (F-SC40FA) provides rigid panel mounting at the rod end, and the standard PT1/4 port thread ensures straightforward pneumatic connection.

The 800 mm stroke and 628 N push force at 0.5 MPa reliably raise and lower a gate or stop blade on a packaging conveyor line, with magnetic sensors confirming the open/closed position.
Moves a lightweight gripper or vacuum cup between two stations 800 mm apart. The front flange mount provides a stable, rigid attachment to the machine frame, and the built-in magnet enables end-of-stroke sensing.
Pushes a single pallet from the bottom of a stack with 628 N of force. The long 800 mm reach clears the dispenser frame, and the tie-rod construction handles the repetitive impact of pallet handling.
For higher force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore (402 N at 0.5 MPa) may suffice. At 800 mm stroke, the 16 mm rod is susceptible to bending under side loads—consider an external linear guide or a guided cylinder if the load is not purely axial.
To replace an existing cylinder, match five points: 40 mm bore, 800 mm stroke, PT1/4 port thread, FA front flange mounting, and the built-in magnet for sensor compatibility. The SC is a tie-rod cylinder, shorter than ISO 15552 profiles, so dimensional interchangeability is limited to other AirTAC SC tie-rod units.
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 indicates a built-in magnet, so you can directly mount CMSG (reed) or DMSG/EMSG (solid-state) sensors on the barrel to detect piston position without external brackets.
