About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75FA
The SC200X75FA is a robust double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 200 mm bore with a 75 mm stroke. It generates a substantial push force of 15708 N at 0.5 MPa and can reach 28274 N at the maximum operating pressure of 0.9 MPa, making it a powerful actuator for heavy-duty industrial tasks.
This model features a 40 mm diameter piston rod with an M36x2 thread and is equipped with an FA front rectangular flange (F-SC200FA) for secure panel or end-face mounting. The cylinder body length is 244 mm, and it includes an adjustable air cushion of 33 mm to decelerate the piston smoothly at the end of its stroke.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75FA Is Used
Heavy Press Tool Actuation
Provides the high force required for operating clamps, punches, and forming tools in large hydraulic-style press replacements, where 15708 N at 0.5 MPa ensures firm material engagement.
Industrial Damper & Gate Control
Ideal for moving large dampers, diverter gates, or heavy baffles in material handling and processing lines, with the front flange mount providing a rigid, fixed installation point.
Lifting & Heavy Part Ejection
Suitable for lifting heavy components or ejecting large parts from molds and fixtures, leveraging the cylinder's high force output and robust 40 mm rod to handle substantial loads.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75FA the Right Cylinder?
When sizing, consider that stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa, while the 200 mm bore provides a significant power increase for demanding applications. For this 75 mm stroke, side loading is typically not a primary concern, but always ensure the load is guided externally if any lateral forces are present.
To guarantee a correct replacement, match five key specifications: the 200 mm bore, the 75 mm stroke, the PT1/2 port thread, the FA front flange mounting accessory, and the absence of a built-in magnet. This ensures dimensional and functional interchangeability with an existing AirTAC SC tie-rod cylinder.
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 SC200X75FA 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 SC200X75FA is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston can drift or drop under load. For load-holding applications, you must use an external mechanical lock, a rod brake, or a pilot-operated check valve.
