About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X120
The AirTAC SC200X120 is a robust double-acting tie-rod cylinder delivering 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 40 mm diameter piston rod, this model is built for heavy industrial linear motion where substantial force is required in a compact 120 mm stroke.
This cylinder features a 244 mm body length (A dimension) and a 33 mm adjustable air cushion at each end, effectively decelerating high-inertia loads to reduce end-of-stroke impact. The standard PT3/4 ports and M36x2 rod thread ensure secure, high-flow connections for demanding pneumatic circuits.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X120 Is Used
Sawmill Log Handling
Powers log stops, kickers, and carriage drives in sawmills, providing the high force needed to position heavy timber safely and reliably.
Heavy Gauge Metal Forming
Provides the clamping force for bending and forming thick metal plates in hydraulic-free pneumatic press tools, ensuring consistent part quality.
Bulk Material Gate Control
Actuates large slide gates on silos, hoppers, and chutes for controlling the flow of grain, aggregate, or biomass in processing facilities.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X120 the Right Cylinder?
Select the SC200X120 when your application demands a force class around 15708 N at standard plant pressure. If your load requires slightly less force and a lighter assembly, consider stepping down to the 160 mm bore (10053 N at 0.5 MPa). For maximum force in the SC family, the 250 mm bore offers 24544 N. Always match replacements on five points: 200 mm bore, 120 mm stroke, PT3/4 port thread, basic mounting, and the absence of a magnet.
For this 120 mm stroke, the rigid 40 mm rod and tie-rod construction handle direct axial loads well. If the application introduces side loads, external guide rails or a guided cylinder are recommended to protect the rod bearing and seals from premature wear.
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 SC200X120 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 reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement for another AirTAC SC200 tie-rod cylinder or an equivalent tie-rod design matching the 200 mm bore, 120 mm stroke, and PT3/4 port thread.
