About the Airtac SC50 Standard Cylinder SC50X400SFA
The AirTAC SC50X400SFA is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling up to 1767 N at 0.9 MPa. Its 50 mm bore and 400 mm stroke suit mid-range linear actuation tasks where a compact tie-rod design is preferred over bulkier ISO 15552 profiles.
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. The front rectangular flange (FA, part F-SC50FA) allows rigid panel or bulkhead mounting. With a 20 mm diameter rod, M16x1.5 rod thread, and 21 mm adjustable air cushion, it handles frequent cycling reliably within a -20 to +70 °C range.

Where the Airtac SC50 Standard Cylinder SC50X400SFA Is Used
Automated Assembly Presses
Provides 1767 N of pressing force at 0.9 MPa for inserting bearings, bushings, or pins in automated assembly stations, with sensor confirmation of full extension.
Product Sorting Gates
Actuates diverter gates on conveyor lines. The 400 mm stroke gives ample travel for wide chutes, while the magnet confirms gate position for interlocked control systems.
Packaging Machinery
Drives sealing jaws or carton folding arms in packaging equipment. The front flange mount secures the cylinder rigidly to the machine frame for consistent, repeatable motion.
Is the Airtac SC50 Standard Cylinder SC50X400SFA the Right Cylinder?
Select the SC50X400SFA when your application requires around 1000 N of force at standard plant pressure. If your load is lighter, stepping down to a 40 mm bore (628 N at 0.5 MPa) can reduce air consumption. For heavier loads, the 63 mm bore provides 1559 N. At 400 mm stroke, ensure the rod is guided externally if side loads are present; the 20 mm rod can experience bending moments under unsupported lateral forces. For replacement, match bore (50 mm), stroke (400 mm), PT port thread, FA front flange mount, and the magnet option (-S) to ensure sensor compatibility.
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 SC50X400SFA FAQ
At 0.5 MPa (5 bar) air pressure, 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 reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
It is a direct replacement for another AirTAC SC50X400 with a front flange mount and magnet. To replace a different brand, verify the bore (50 mm), stroke (400 mm), PT port size (1/4 inch), front flange mounting dimensions (F-SC50FA), and the presence of a magnetic piston for sensors.
