About the Airtac SC50 Standard Cylinder SC50X320N
The SC50X320N is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 320 mm stroke. It generates a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, making it a solid mid-range actuator for general industrial automation.
This model is fitted with NBR (nitrile) seals as standard, suitable for operating temperatures from -20 to +70 °C. The 20 mm diameter piston rod and PT1/4 ports provide reliable fluid handling, while the 21 mm adjustable air cushion at each end helps decelerate the piston smoothly, reducing end-of-stroke impact.

Where the Airtac SC50 Standard Cylinder SC50X320N Is Used
Material Transfer Gates
Provides the 982 N push at 0.5 MPa needed to reliably actuate diverter gates and stops on packaging and assembly conveyors with a 320 mm travel.
Clamping & Fixturing
Delivers consistent clamping force for medium-duty CNC fixtures and welding jigs, with NBR seals offering good wear resistance in typical shop air conditions.
Product Pushers & Ejectors
The 320 mm stroke is ideal for pushing cartons or components off a line, providing a clean, repeatable motion with adjustable cushioning to handle varying loads smoothly.
Is the Airtac SC50 Standard Cylinder SC50X320N the Right Cylinder?
For applications requiring higher force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at the same 0.5 MPa pressure. If space is a constraint and less force is acceptable, the 40 mm bore SC40 series delivers 628 N. This 320 mm stroke is within the standard range for the 50 mm bore, which goes up to 1200 mm.
For strokes of this length, ensure the load is guided and side forces are minimized to prevent bending stress on the 20 mm rod. When replacing an existing cylinder, match five key points: 50 mm bore, 320 mm stroke, PT port thread, basic mounting (no bracket), and the absence of a built-in magnet.
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 SC50X320N FAQ
At the standard operating pressure of 0.5 MPa, 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X320N is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston rod can drift or drop. For load-holding applications, an external rod lock or a pilot-operated check valve must be added to the circuit.
