About the Airtac SC50 Standard Cylinder SC50X100SFA
The AirTAC SC50X100SFA is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for a 100 mm stroke, making it a solid mid-range actuator for general industrial automation.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, eliminating the need for external switch rails. The front rectangular flange (FA, part F-SC50FA) allows secure panel or bulkhead mounting, while the standard PT1/4 port and TPU seals suit typical compressed-air environments from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X100SFA Is Used
Clamping & Holding Fixtures
The 982 N push force at 0.5 MPa is ideal for pneumatic clamping, pressing, and holding small parts during assembly or machining, with sensor confirmation via the built-in magnet.
Part Stops & Diverters
Use this 100 mm stroke cylinder as a robust part stop or diverter gate on conveyor lines. The FA flange mounts rigidly to a frame, and the magnetic piston enables end-of-stroke detection.
Packaging & Eject Mechanisms
Reliable ejection of packaged goods or cartons from a line. The adjustable cushion protects the cylinder and product at the end of the 100 mm stroke, even at speeds up to 800 mm/s.
Is the Airtac SC50 Standard Cylinder SC50X100SFA the Right Cylinder?
For applications needing slightly more force, step up to the SC63 bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 offers 628 N. The SC50X100SFA is factory-configured with a magnet and FA flange—when replacing an existing unit, match bore, stroke, PT port thread, the -S magnet option, and the FA front-flange mounting to ensure drop-in compatibility.
At 100 mm stroke, side-load bending is minimal, but always align the rod with the load axis and avoid direct lateral forces to preserve bearing life.
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 SC50X100SFA FAQ
At 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, push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position without extra brackets.
