About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X320
The AirTAC SC200X320 is a double-acting tie-rod cylinder delivering a substantial 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa). With a 200 mm bore and a 320 mm stroke, this actuator is built for heavy linear motion tasks. The 40 mm diameter piston rod and 33 mm adjustable air cushion provide robust guidance and smooth end-of-stroke deceleration.
This model features PT3/4 port threads and a body length A of 244 mm, resulting in a total extended length of approximately 564 mm. As a genuine AirTAC SC series cylinder, it offers a compact, non-ISO 15552 tie-rod design that is shorter than profile cylinders, making it a direct fit for existing AirTAC SC200 installations.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X320 Is Used
Heavy Press & Forming
Generating over 28000 N of force at 0.9 MPa, the SC200X320 powers heavy-duty pressing, clamping, and metal forming operations where consistent, high-force actuation is critical.
Pallet & Load Transfer
Ideal for pushing or lifting heavy pallets and loads on conveyor systems. The 320 mm stroke provides the reach needed for cross-transfer mechanisms in logistics hubs.
Large Valve Actuation
Provides the high thrust required to operate large industrial gate or butterfly valves. The adjustable air cushion ensures smooth operation, protecting the valve stem from impact damage.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X320 the Right Cylinder?
For applications needing less force, stepping down to an SC160 bore reduces push force to 10053 N at 0.5 MPa, while an SC250 bore increases it to 24544 N. At a 320 mm stroke, ensure the load is guided externally to prevent excessive side load on the 40 mm rod and rod bearing, which can cause bending or premature seal wear. For a direct replacement, match the 200 mm bore, 320 mm stroke, PT3/4 port thread, basic mounting, and confirm the magnet option (this model has no built-in 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 SC200X320 FAQ
At the standard operating pressure of 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.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a standard ISO 15552 profile cylinder. It is a direct dimensional replacement only for another AirTAC SC200 tie-rod cylinder with the same bore, stroke, and port thread.
