The AirTAC Airtac SC40 Standard Cylinder SC40X200SFB 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 SC40X200SFB is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and 200 mm stroke, this model features a 16 mm diameter piston rod and an adjustable air cushion length of 21 mm to decelerate the load smoothly at the end of travel.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and an FB rear rectangular flange (accessory F-SC40FB) for rigid end-face mounting. The body length A is 142 mm, making the total extended length approximately 342 mm. It uses standard PT ports (PT1/4) and TPU seals for operation in ambient temperatures from -20 to +70 °C.

The 200 mm stroke and 628 N force at 0.5 MPa make this cylinder ideal for ejecting or diverting small packages from a conveyor line, with the rear flange providing a rigid, space-efficient mount against a machine frame.
Delivers a controlled 1130 N clamping force at 0.9 MPa for holding workpieces during drilling or light machining. The built-in magnet enables end-of-stroke sensing to confirm the clamp is fully engaged before the cycle starts.
Suitable for light press-fit operations up to 1130 N. The adjustable cushion absorbs impact energy at the end of the press stroke, protecting tooling and the cylinder from shock loads.
Select the SC40 bore when your application requires a push force between 528 N and 1130 N. If your load demands more force, step up to the SC50 bore, which provides 982 N at 0.5 MPa. For lighter, more compact needs, the SC32 bore offers 402 N at the same pressure. For a successful replacement, match these five points: bore (40 mm), stroke (200 mm), port thread (PT1/4), rear flange mounting (FB), and the built-in magnet (-S) for sensor compatibility.
At a 200 mm stroke, the SC40's standard rod bearing provides good support for purely axial loads. If your application involves any side load, even a small one, an external guide rail or a guided cylinder is strongly recommended to prevent rod bending and premature seal wear.
Quick checklist
At the standard operating pressure of 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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
This is a tie-rod cylinder, not an ISO 15552 profile cylinder. To ensure a direct fit, verify the replacement unit matches these five specifications: a 40 mm bore, a 200 mm stroke, a PT1/4 port thread, an FB rear flange mounting, and a built-in magnet for sensors. The body length A is 142 mm, which is shorter than a comparable ISO 15552 cylinder.
