About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X480FA
The AirTAC SC250X480FA is a large-bore double-acting tie-rod cylinder delivering a substantial push force of 24544 N at 0.5 MPa (44178 N at the maximum operating pressure of 0.9 MPa). With a 50 mm diameter piston rod and a 480 mm stroke, this ISO 6430 class actuator is built for heavy industrial linear motion tasks where high force and structural rigidity are non-negotiable.
This specific model is configured with a front rectangular flange (FA) for secure panel or bulkhead mounting, using accessory F-SC250FA. The adjustable air cushion (40 mm length) decelerates the 250 mm bore piston smoothly, protecting the end caps during high-energy stops. Ports are PT 1 inch, and the standard TPU seals provide reliable operation from -20 to +70 C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X480FA Is Used
Heavy Press & Forming
Provides up to 44178 N of force for stamping, bending, or compression jigs in metal fabrication cells.
Marine Hatch Actuation
The 480 mm stroke and high force operate large watertight doors or cargo hatches, with the front flange simplifying bulkhead mounting.
Large-Scale Clamping
Secures massive workpieces on CNC gantry mills or welding positioners, maintaining clamp force with its 250 mm bore piston.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X480FA the Right Cylinder?
Choose the SC250 when your application requires a push force above 18095 N at 0.9 MPa, which is the limit of the next smaller SC160 bore. If your load is lighter, stepping down to the SC200 (28274 N at 0.9 MPa) can reduce air consumption and physical footprint. For strokes of 480 mm, ensure the rod is not subjected to significant side loading; the 50 mm rod is robust, but external guides or a guided cylinder should be used if bending moments are present.
For a direct replacement, match five key points: 250 mm bore, 480 mm stroke, PT 1 inch ports, front flange FA mounting, and the absence of a magnet. This SC250X480FA is dimensionally interchangeable only with another AirTAC SC250 of the same configuration, as the SC tie-rod series is shorter than ISO 15552 profiles.
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 SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X480FA FAQ
At 0.5 MPa, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, push force reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The SC250 is a double-acting cylinder and does not lock or hold position when pressure is exhausted or the valve is centered. The piston will drift under load. For load holding, you must add an external rod brake, a mechanical lock, or pilot-operated check valves in the circuit.
