About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300FA
The SC200X300FA is a large-bore double-acting pneumatic cylinder delivering a substantial 15708 N of push force at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore and a 300 mm stroke, this model is configured with a front rectangular flange (FA) for rigid, panel-style mounting, making it ideal for heavy-duty pressing and clamping fixtures.
This tie-rod cylinder features a 40 mm diameter piston rod with an M36x2 male thread and PT3/4 port connections. The total extended body length is approximately 544 mm, calculated from its 244 mm body length plus the 300 mm stroke. It includes an adjustable air cushion with a 33 mm cushion length to decelerate high-inertia loads at the end of travel.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300FA Is Used
Heavy-Duty Press Frames
Generates up to 28274 N of force at 0.9 MPa for industrial pressing, stamping, or die-casting ejection systems requiring a rigid front-flange mount.
Large Component Clamping
Provides stable, high-force clamping for welding fixtures or machining centers processing large steel fabrications, with the FA flange ensuring precise alignment.
Material Forming Equipment
Suitable for bending or forming thick sheet metal and composite materials, where the 300 mm stroke provides the necessary linear travel for deep-draw operations.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300FA the Right Cylinder?
For applications requiring slightly less force, stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa, while the 250 mm bore offers a significant jump to 24544 N. At a 300 mm stroke, the 40 mm rod is robust, but if the load is not guided and side forces are present, an external guide rail or a guided cylinder should be used to prevent rod bearing wear and bending.
To ensure a correct drop-in replacement, match five key specifications: the 200 mm bore, the 300 mm stroke, the PT3/4 port thread, the FA front flange mounting (accessory F-SC200FA), and the absence of a built-in magnet. This cylinder uses the standard TPU seal material for a temperature range of -20 to +70 °C.
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 SC200X300FA FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 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. The AirTAC SC series is a tie-rod cylinder that is physically shorter than a standard ISO 15552 cylinder. It will only directly interchange with another AirTAC SC200 tie-rod cylinder that matches the 300 mm stroke, PT3/4 ports, and FA front flange mount.
