About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350TC
The SC200X350TC is a large-bore double-acting pneumatic cylinder delivering substantial force for demanding industrial tasks. At 0.5 MPa air pressure, it generates 15708 N of push force and 15080 N on the pull stroke, while at the maximum 0.9 MPa operating pressure, thrust reaches 28274 N—enough to handle heavy pressing, clamping, and lifting operations.
This model features a 350 mm stroke with a 40 mm diameter piston rod and M36x2 rod thread. The body length A is 244 mm, giving a total extended length of approximately 594 mm. Equipped with a centre trunnion (TC) mount including the TCM1 bracket (order code F-SC200TC), it is designed to pivot during operation, absorbing angular movement in the application.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350TC Is Used
Heavy-Duty Clamping
Applies up to 28274 N of force at 0.9 MPa for securely holding large workpieces during welding, machining, or assembly processes.
Material Forming Presses
Ideal for small to medium forming, bending, or stamping operations where a controlled, high-force linear stroke is required with pivoting movement.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder to swing, making it suitable for actuating heavy diverter gates or sorting mechanisms on conveyor lines.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350TC the Right Cylinder?
For applications needing slightly less force, consider the SC160 bore which provides 10053 N push at 0.5 MPa. If your load requires the full 200 mm bore force but a different stroke, verify the stroke stays within the 1500 mm maximum standard stroke for this bore. This 350 mm stroke is well within the standard range.
When replacing an existing cylinder, match five key points: 200 mm bore, 350 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC200TC bracket, and no magnet. For strokes over 300 mm like this one, ensure the rod is not subjected to significant side loads; use external linear guides or a guided cylinder configuration to prevent rod bending and premature bearing 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 SC200X350TC 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. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder of the same bore and stroke, so it is not dimensionally interchangeable. This 200 mm bore model is classified as an ISO 6430 class cylinder. Replace it only with another AirTAC SC200 tie-rod cylinder matching the bore, stroke, mounting, and port thread.
