About the Airtac SC50 Standard Cylinder SC50X240H
The SC50X240H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, configured with a 50 mm bore and a 240 mm stroke. It produces a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator for industrial tasks.
This model is equipped with high-temperature Viton (FKM) seals, extending the operating temperature range to 0–150 °C, ideal for autoclaves, foundries, or drying equipment. The 20 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration, while the PT1/4 port and M16x1.5 rod thread provide standard connectivity.

Where the Airtac SC50 Standard Cylinder SC50X240H Is Used
Hot-Zone Automation
The Viton seals withstand 150°C, making this cylinder reliable for actuating gates, diverters, or clamps inside industrial ovens, autoclaves, and heated presses.
Material Handling
With 982 N of push force at 0.5 MPa, it efficiently operates pushers, stops, and transfer mechanisms on packaging and assembly lines requiring a 240 mm stroke.
Clamping & Pressing
Delivers up to 1767 N of clamping force at 0.9 MPa for holding parts during welding, gluing, or machining operations in high-temperature environments.
Is the Airtac SC50 Standard Cylinder SC50X240H the Right Cylinder?
Select the SC50 bore when your application requires between 825 N (pull) and 982 N (push) at standard 0.5 MPa shop air. If you need more force, step up to the SC63 bore which provides 1559 N push at the same pressure. For a lighter, more compact solution, the SC40 bore delivers 628 N push.
To ensure a direct replacement, match five key points: 50 mm bore, 240 mm stroke, PT port thread, the basic (no bracket) mounting configuration, and the absence of a magnet. This cylinder is not dimensionally interchangeable with ISO 15552 profiles, so verify tie-rod mounting dimensions.
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 SC50X240H FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides 982 N of pushing force and 825 N of pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No. The SC50X240H is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
