About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350H
The AirTAC SC200X350H is a double-acting, single-rod tie-rod cylinder with a 200 mm bore and 350 mm stroke, fitted with high-temperature Viton (FKM) seals for reliable operation in environments from 0 to +150 °C. This model 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 suitable for heavy industrial actuation.
With a 40 mm diameter piston rod and a 33 mm adjustable air cushion at each end, the cylinder decelerates high inertial loads smoothly, reducing impact stress. The body length A is 244 mm, giving a total extended length of approximately 594 mm. PT3/4 port threads and an M36x2 rod thread provide robust, standard fluid connections for high-flow pneumatic circuits.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350H Is Used
Heavy Press & Forming
The 28274 N force at 0.9 MPa drives large forming dies and heavy-duty presses, with Viton seals ensuring durability in high-temperature tooling environments.
High-Temperature Material Handling
Operates reliably up to 150°C in foundry or autoclave loading systems, pushing heavy pallets or castings where standard seals would degrade.
Large Valve Actuation
Provides the high thrust required to stroke large industrial gate or butterfly valves in process plants, with an adjustable cushion to handle the valve's end-of-travel inertia.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350H the Right Cylinder?
Select the SC200 bore for applications requiring push forces above 15000 N at standard plant pressure; if your load demands less than 10000 N, stepping down to the SC160 bore (10053 N at 0.5 MPa) can reduce air consumption and physical size. For this 350 mm stroke, ensure the load is guided externally if significant side forces are present, as the 40 mm rod can experience bending moments under unsupported lateral loads.
To replace an existing unit, match five key points: 200 mm bore, 350 mm stroke, PT port thread, basic mounting (no integrated bracket), and the absence of a built-in magnet. This H-suffix model uses Viton seals, so it is a direct replacement only for cylinders specified for high-temperature service.
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 SC200X350H FAQ
At 0.5 MPa, the cylinder delivers 15708 N pushing and 15080 N pulling. 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 with a shorter body length than an ISO 15552 cylinder of the same bore and stroke, so it is not dimensionally interchangeable. It can replace another AirTAC SC200 tie-rod cylinder with matching bore, stroke, port thread, and mounting.
