About the Airtac SC50 Standard Cylinder SC50X6
The SC50X6 is a double-acting tie-rod cylinder built for very short, precise linear strokes. With a 50 mm bore and just 6 mm of travel, it produces a push force of 982 N at 0.5 MPa (1374 N at 0.7 MPa), making it suitable for clamping, ejecting, or positioning where space is tight.
Its body length A is 150 mm, and the 20 mm diameter piston rod with M16x1.5 male thread provides excellent rigidity for this short stroke. The cylinder uses PT1/4 ports and includes an adjustable air cushion (21 mm long) to soften end-of-stroke impact even in rapid cycling. Operating pressure range is 0.15-1.0 MPa with standard TPU seals rated for -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X6 Is Used
Short-Stroke Clamping
Delivers 982 N at 0.5 MPa for compact fixture clamping. The 6 mm stroke provides just enough travel to engage and release workpieces in tight automation cells.
Part Ejection & Stamping
Rapid 6 mm punch or eject motion in stamping dies and assembly stations. The adjustable cushion protects tooling from impact at cycle end.
Diverter Gate Actuation
Operates small diverter gates or stops on conveyor lines. The short stroke and 20 mm rod resist deflection under quick-acting pneumatic control.
Is the Airtac SC50 Standard Cylinder SC50X6 the Right Cylinder?
For a 50 mm bore, this 6 mm stroke is well within the standard range (max 1200 mm). If you need slightly more force, stepping up to a 63 mm bore delivers 1559 N push at 0.5 MPa. For side-loaded applications, even a short stroke can transmit bending moment to the rod bearing; consider an external guide or a guided cylinder if the load is not purely axial.
When replacing an existing cylinder, match five key points: 50 mm bore, 6 mm stroke, PT1/4 port thread, basic mount (no accessory brackets), and no magnet. This model uses the default TPU seal and PT thread.
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 SC50X6 FAQ
At 0.7 MPa operating pressure, the SC50X6 generates 1374 N of push force. The pull force at the same pressure is 825 N (accounting for the 20 mm rod area). Maximum theoretical force at 1.0 MPa is 200 kgf.
It replaces any tie-rod cylinder matching 50 mm bore, 6 mm stroke, PT1/4 ports, and basic mounting. The SC series is not ISO 15552 interchangeable; its body length A=150 mm is shorter. Always verify port size and mounting dimensions against your existing setup.
