About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X550
The SC200X550 is a large-bore double-acting pneumatic cylinder delivering 15708 N of push force at just 0.5 MPa, scaling to a substantial 28274 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 550 mm stroke, it is built for heavy linear actuation tasks that require significant force over a moderate distance.
This model features a body length of 244 mm and an adjustable air cushion length of 33 mm to decelerate high-inertia loads smoothly. As a tie-rod cylinder, it is shorter than an equivalent ISO 15552 profile, making it a space-efficient choice for heavy-duty machinery where genuine AirTAC reliability is required.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X550 Is Used
Heavy Press and Clamping
Provides up to 28274 N of force at 0.9 MPa for powerful clamping, pressing, and riveting operations in metal fabrication and assembly lines.
Material Handling Pushers
Ideal for diverting or pushing heavy pallets and bulk materials on large conveyor systems, using its 550 mm stroke to transfer loads completely.
Large Component Ejection
Delivers the high ejection force needed to release large, heavy molded parts from industrial molds, ensuring reliable cycle times in plastics and die-casting.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X550 the Right Cylinder?
For applications needing less force, consider stepping down to a 160 mm bore (10053 N at 0.5 MPa). If your load requires even greater thrust, the 250 mm bore model provides 24544 N at the same pressure. The 550 mm stroke on a 40 mm rod is robust, but always assess side loads; for strokes over 300 mm with any lateral force, use an external guide or a guided cylinder to prevent rod bending and premature bearing wear. To ensure a correct drop-in replacement, match all five key points: 200 mm bore, 550 mm stroke, PT port thread, basic (no mounting accessory), and no magnet.
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 SC200X550 FAQ
At the standard 0.5 MPa operating pressure, 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.
No, the SC200X550 is a double-acting cylinder and will not hold its position if air pressure is lost or the 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.
