About the Airtac SC50 Standard Cylinder SC50X225SFA
The AirTAC SC50X225SFA is a double-acting single-rod tie-rod cylinder with a 50 mm bore and 225 mm stroke, delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors on the barrel for reliable end-of-stroke detection without external brackets.
This model includes an FA front rectangular flange (F-SC50FA) for secure panel mounting on the rod side. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the standard PT1/4 port thread ensures straightforward pneumatic connection.

Where the Airtac SC50 Standard Cylinder SC50X225SFA Is Used
Automated Press Fitting
The 982 N push force at 0.5 MPa is ideal for light press-fit assembly operations, inserting bearings or bushings with controlled pneumatic pressure and sensor-confirmed stroke completion.
Part Rejection Gate
Actuate a high-speed diverter gate on a conveyor line. The front flange mount provides rigid panel attachment, and the magnetic piston allows position feedback to confirm gate open/close status.
Pallet Stop & Release
Control pallet flow in gravity or powered roller systems. The 225 mm stroke provides ample travel for a robust stop blade, and the adjustable cushion absorbs impact energy for long service life.
Is the Airtac SC50 Standard Cylinder SC50X225SFA the Right Cylinder?
Choose the SC50 when 982 N at 0.5 MPa meets your load requirement. If you need more force, step up to the SC63 bore offering 1559 N at the same pressure. For lighter, faster applications, the SC40 provides 628 N. The 225 mm stroke is within the 1200 mm maximum standard stroke for this bore.
For replacement, match five points: 50 mm bore, 225 mm stroke, PT port thread, FA front flange mounting, and the -S magnet option for sensor compatibility. Always use an external guide or guided cylinder when the rod is exposed to side loads, as tie-rod cylinders are designed for axial thrust only.
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 SC50X225SFA FAQ
At 0.5 MPa operating pressure, the cylinder produces 982 N extending (push) and 825 N retracting (pull). At 0.7 MPa, push force increases to 1374 N. The maximum theoretical force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and overall length are not interchangeable. It directly replaces another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT port, FA flange, and magnet option.
