About the Airtac SC50 Standard Cylinder SC50X225SFB
The AirTAC SC50X225SFB is a 50 mm bore double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 225 mm stroke suits medium-reach clamping and pressing tasks, with a 20 mm diameter piston rod providing good rigidity for inline loads.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The FB rear rectangular flange (F-SC50FB) allows rigid panel mounting from the cap end, and the standard TPU seals ensure reliable operation from -20 to +70 °C with PT1/4 ports.

Where the Airtac SC50 Standard Cylinder SC50X225SFB Is Used
Sensor-Monitored Clamping
The built-in magnet and FB rear flange suit automated jigs where magnetic sensors confirm clamp/unclamp status before the next machine cycle starts.
Panel-Mounted Ejector
Rigidly mount this cylinder behind a panel via the rear flange to eject parts from a conveyor line, with 982 N of push force at standard shop air.
Stopping Gate Actuator
Use the 225 mm stroke to raise and lower a stopping gate on a gravity roller conveyor, with sensor confirmation of gate position for interlock safety.
Is the Airtac SC50 Standard Cylinder SC50X225SFB the Right Cylinder?
Choose the SC50 when your application needs around 980 N at 0.5 MPa; if you need more force, step up to the SC63 bore (1559 N at 0.5 MPa). For lighter, faster cycling, the SC40 delivers 628 N. The 225 mm stroke is within the standard range for this bore.
For strokes over 300 mm, side loads become a critical factor—long unsupported rods can bend under lateral force. Use an external linear guide or switch to a guided cylinder to protect the rod bearing. When replacing, match five points: 50 mm bore, 225 mm stroke, PT1/4 ports, FB rear flange mount, and the -S magnet option.
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 SC50X225SFB FAQ
At 0.7 MPa (7 bar) supply pressure, the SC50 bore generates 1374 N of push force and 825 N of pull force on the retract stroke. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, provided the original is also a 50 mm bore, 225 mm stroke, PT-port, rear-flange (FB) cylinder with a magnet. The SC series is a tie-rod design, so it is not dimensionally interchangeable with ISO 15552 profile cylinders.
