About the Airtac SC100 Standard Cylinder SC100X50SFA
The SC100X50SFA is a double-acting pneumatic cylinder delivering a robust 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 50 mm stroke and 25 mm diameter piston rod are well-suited for short, high-force clamping, pressing, or ejecting tasks where space is tight.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The FA front rectangular flange (F-SC100FA) allows the cylinder to be rigidly bolted to a machine panel from the rod end, ensuring stable alignment for the 100 mm bore body.

Where the Airtac SC100 Standard Cylinder SC100X50SFA Is Used
High-Force Clamping
Generates up to 7068 N at 0.9 MPa for securely holding heavy workpieces during machining or welding operations.
Automated Ejection
The short, powerful stroke is ideal for ejecting parts from molds or stamping dies, with sensor confirmation of full retraction.
Heavy Part Stops
Acts as a robust end-stop on heavy-duty conveyor lines, stopping pallets or large components with consistent force.
Is the Airtac SC100 Standard Cylinder SC100X50SFA the Right Cylinder?
For applications needing less force, consider stepping down to an 80 mm bore (2513 N push at 0.5 MPa). If a longer stroke is required, the SC100 bore supports standard strokes up to 1500 mm. This short 50 mm stroke minimizes rod bearing wear, but always ensure the load is guided externally to prevent side forces from acting on the rod.
To replace an existing cylinder, match five key points: 100 mm bore, 50 mm stroke, PT port thread, FA front flange mounting, and the -S magnet for sensor compatibility. This ensures a direct dimensional and functional swap.

- ✓ 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 SC100 Standard Cylinder SC100X50SFA FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N. At the maximum operating pressure of 0.9 MPa, it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes, the -S suffix indicates a built-in magnet. This allows you to directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel to detect piston position.
