About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X260TC
The SC200X260TC is a large-bore double-acting pneumatic cylinder delivering substantial linear force for heavy-duty industrial automation. At 0.5 MPa it produces 15708 N pushing and 15080 N pulling, rising to 28274 N at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, clamping, and lifting large payloads.
This model features a 200 mm bore, 40 mm piston rod with M36x2 thread, and a 260 mm stroke well within the 1500 mm maximum standard stroke for this bore. The TC suffix specifies a centre trunnion mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to pivot during operation. Adjustable pneumatic cushioning decelerates the 40 mm cushion stroke at each end, protecting the end caps from impact.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X260TC Is Used
Heavy Press & Clamp Fixtures
Generates over 28 kN of force at 0.9 MPa for holding large workpieces during welding, machining, or assembly operations.
Material Handling & Lifting
Provides the push force needed to lift and transfer heavy pallets or steel sheets on conveyor lines, with the trunnion mount allowing a pivoting lift motion.
Large Valve & Damper Actuation
Operates heavy-duty process valves and dampers in water treatment or power generation plants, where high thrust and a pivoting mount are required.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X260TC the Right Cylinder?
For applications needing less force, stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa. The SC200X260TC is an ISO 6430 class tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. When replacing, match five points exactly: 200 mm bore, 260 mm stroke, PT port thread, centre trunnion (TC) mounting, and the absence of a magnet. The 260 mm stroke with a 40 mm rod is robust, but any significant side load should be managed with an external guide to prevent rod 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 SC200X260TC FAQ
At 0.5 MPa, the cylinder pushes with 15708 N and pulls with 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 SC200X260TC is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston can drift. For load holding, an external pilot-operated check valve or mechanical rod lock must be added to the circuit.
