The AirTAC Airtac SC40 Standard Cylinder SC40X220SFA is a genuine double-acting standard air cylinder with a Ø40mm bore and 220mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X220SFA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (879 N at 0.7 MPa), built around a 16 mm diameter piston rod for robust linear actuation. Its 220 mm stroke is well within the 1200 mm maximum standard range for the 40 mm bore, making it a standard-configuration unit with a total extended body length of approximately 362 mm.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-stroke position feedback without external brackets. The FA suffix denotes a front rectangular flange (F-SC40FA), which mounts the cylinder rigidly from the rod-end cap onto a machine panel, ideal for push applications where the cylinder body must be fixed perpendicular to the mounting surface.

The 628 N push force at 0.5 MPa and 220 mm stroke are well-suited for diverting lightweight packages or components on a conveyor line, with the front flange providing a stable, perpendicular mounting face.
With a built-in magnet for sensor confirmation, this cylinder reliably actuates clamps on assembly jigs. The 16 mm rod resists deflection under the direct clamping forces typical in machining fixtures.
Ideal as a low-profile pusher arm in palletising cells, the front flange mount secures the cylinder end-on to the frame, while the 220 mm stroke pushes cartons squarely onto a pallet.
For applications requiring slightly more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa, while the 32 mm bore offers a more compact alternative at 402 N. This 40 mm bore size balances a 16 mm rod with a PT1/4 port for responsive cycle times.
To ensure a direct form-fit-function replacement, match five key points: 40 mm bore, 220 mm stroke, PT port thread, front flange (FA) mounting accessory, and the built-in magnet (-S) for sensor compatibility. The 220 mm stroke is moderate, but if the rod is subjected to side loading, an external linear guide should be used to prevent bending stress on the rod bearing.
Quick checklist
At the standard 0.5 MPa operating pressure, this 40 mm bore cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
It is a direct replacement for another AirTAC SC tie-rod cylinder of the same 40 mm bore, 220 mm stroke, PT ports, front flange (FA) mount, and built-in magnet. It is not dimensionally interchangeable with ISO 15552 profile cylinders.
