About the Airtac SC50 Standard Cylinder SC50X106
The SC50X106 is a double-acting tie-rod cylinder from the AirTAC SC series, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 1.0 MPa. With a 50 mm bore and a 106 mm stroke, this model is built for short-to-medium linear actuation tasks where a compact footprint is essential—the body length A is just 150 mm.
A 20 mm diameter piston rod and M16x1.5 rod thread provide solid mechanical connection, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact. The standard PT1/4 port thread and TPU seals suit filtered-air systems operating from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X106 Is Used
Part Stops & Gates
The 106 mm stroke and 982 N push force at 0.5 MPa are well-suited for actuating part stops, diverters, or small gates on light-duty conveyor lines.
Clamping & Pressing
Delivers up to 1767 N of clamping force at 1.0 MPa for holding workpieces in jigs, fixtures, or light assembly presses where a short, controlled stroke is needed.
Packaging Ejectors
The compact body (150 mm A-length) and tie-rod construction make it easy to mount in tight packaging machines for ejecting or sorting small cartons and products.
Is the Airtac SC50 Standard Cylinder SC50X106 the Right Cylinder?
For applications needing slightly more force at the same pressure, stepping up to the 63 mm bore (SC63 series) provides 1559 N push at 0.5 MPa. If a lighter, more compact actuator is acceptable, the 40 mm bore delivers 628 N. When replacing an existing cylinder, match five points: 50 mm bore, 106 mm stroke, PT1/4 port thread, the specific mounting accessory (this basic model has none), and confirm whether a magnet is required—this code has no -S suffix, so no built-in magnet is present. For strokes over 300 mm on this rod size, consider an external guide to protect the rod bearing from side loads.
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 SC50X106 FAQ
At 0.7 MPa operating pressure, the SC50X106 produces a push force of 1374 N and a pull force of 825 N (the pull force is lower due to the area occupied by the 20 mm rod). The maximum push force at 1.0 MPa is 1767 N.
No. The SC series is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift. For load-holding, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
