About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200TC
The AirTAC SC200X200TC is a large-bore double-acting tie-rod cylinder delivering a substantial 15708 N push force at 0.5 MPa (28274 N at 0.9 MPa). With a 200 mm stroke and a 40 mm diameter piston rod, it is built for heavy linear actuation tasks where pivoting movement is required.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to swing through an arc to accommodate angular misalignment. The adjustable air cushion (33 mm) decelerates the 200 mm bore piston smoothly, protecting end caps during high-cycle operation. Ports are PT1/2.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200TC Is Used
Heavy Press & Clamping
Provides 15.7 kN of force at 0.5 MPa for industrial presses, forming dies, and high-force clamping fixtures in metal fabrication.
Pivoting Conveyor Gates
The TC centre trunnion mount allows the cylinder to pivot, making it ideal for actuating heavy diverter gates or chutes on aggregate and mining conveyors.
Large Damper & Valve Actuation
Delivers the high thrust needed to open and close large industrial dampers, butterfly valves, and hopper doors in processing plants.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200TC the Right Cylinder?
Choose the SC200 for force requirements around 15708 N at standard plant pressure. If your application needs less force, the SC160 bore provides 10053 N at 0.5 MPa in a smaller envelope. For strokes of 300 mm or longer, evaluate side-load conditions carefully—a 40 mm rod extending far can experience bending under off-axis loads; consider an external guide or a guided cylinder configuration.
To ensure a direct replacement, match five key points: 200 mm bore, 200 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the absence of a built-in magnet. This cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC200X200TC 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, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200 is a double-acting cylinder and will not hold position if pressure is lost or the directional valve is centered. The piston can drift or drop. For load holding, you must add a pilot-operated check valve, external rod lock, or mechanical brake.
