About the Airtac SC50 Standard Cylinder SC50X40SFA
The SC50X40SFA is a 50 mm bore double-acting pneumatic cylinder with a short 40 mm stroke, ideal for compact clamping, ejecting, and sorting tasks. With a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa, it provides ample power for light-to-medium industrial actuation within a tight envelope.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke detection without external brackets. It comes equipped with a front rectangular flange (FA, part F-SC50FA) for secure panel or bulkhead mounting, and operates with standard TPU seals on a PT port thread.

Where the Airtac SC50 Standard Cylinder SC50X40SFA Is Used
Automated Clamping
The 40 mm stroke and 982 N force at 0.5 MPa make this cylinder perfect for rapid, repeatable workpiece clamping in CNC jigs and welding fixtures, with sensor confirmation of clamp position.
Part Ejection & Sorting
Ideal for short-throw pushers on conveyor lines to divert or reject products. The front flange mount allows rigid attachment to the conveyor side frame.
Small Press & Assembly
Use this compact cylinder in benchtop pneumatic presses for pressing bearings, pins, or seals. The built-in magnet ensures the ram has fully retracted before the next cycle.
Is the Airtac SC50 Standard Cylinder SC50X40SFA the Right Cylinder?
For applications needing slightly less force in a smaller footprint, the 40 mm bore (628 N at 0.5 MPa) may suffice; for heavier loads, step up to the 63 mm bore (1559 N at 0.5 MPa). The 40 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five key points: 50 mm bore, 40 mm stroke, PT port thread, the FA front flange mounting accessory, and the built-in magnet (-S) for sensor compatibility. This ensures a direct dimensional and functional swap with another AirTAC SC50 tie-rod unit.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X40SFA FAQ
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG series sensors directly onto the barrel's sensor groove to detect piston position without any additional brackets.
