About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X280FA
The AirTAC SC200X280FA is a large-bore double-acting pneumatic cylinder delivering a substantial push force of 15708 N at 0.5 MPa (28274 N at 0.9 MPa). With a 200 mm stroke and a robust 40 mm diameter piston rod, it is built for heavy-duty linear actuation tasks requiring significant power in a compact footprint.
This model features an FA front rectangular flange (F-SC200FA) for secure panel or bulkhead mounting. The tie-rod construction ensures easy maintenance, while the adjustable air cushion at both ends decelerates the 40 mm rod smoothly over a 33 mm cushion length, protecting your machinery from impact damage.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X280FA Is Used
Heavy Press & Clamping
Generates up to 28274 N of force at 0.9 MPa for powerful clamping, pressing, and riveting operations in automotive and metal fabrication cells.
Material Handling Pushers
Ideal for pushing heavy pallets or large components off a conveyor line, where the 200 mm bore provides the necessary thrust to move substantial loads.
Large Valve Actuation
Provides the high force output required to operate large industrial gate valves or diverter gates in processing plants, with a front flange for rigid mounting.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X280FA the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 160 mm bore SC160 series, which provides 10053 N of push force at 0.5 MPa. The FA front flange mount on this SC200X280FA is ideal when the cylinder body must be fixed to a machine panel from the rod end, ensuring precise alignment. When replacing, match the 200 mm bore, 280 mm stroke, PT port thread, FA mounting accessory, and the absence of a magnet sensor option to guarantee a drop-in fit. At this 280 mm stroke, the long 40 mm rod is robust, but avoid significant side loads without an external guide to prevent rod bearing wear and bending.
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 SC200X280FA FAQ
At 0.5 MPa (5 bar), the push force is 15708 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. This is a standard double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston can drift or drop. For load holding, you must add an external pilot-operated check valve or a mechanical rod brake.
