About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200TC
The AirTAC SC250X200TC is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With a 200 mm stroke and a robust 50 mm diameter piston rod, this ISO 6430 class cylinder is built for demanding industrial automation tasks requiring high force in a compact footprint.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC250TC), allowing the cylinder to pivot and accommodate swinging loads. The adjustable air cushion (40 mm length) decelerates the piston smoothly at end-of-stroke, protecting the large end caps. Operating on filtered air from 0.15 to 1.0 MPa, it uses standard PT ports and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200TC Is Used
Heavy Press & Clamping
Generates up to 44178 N of force at 0.9 MPa for powerful clamping, pressing, and riveting operations in metal fabrication and assembly lines.
Material Handling & Lifting
The centre trunnion mount allows the cylinder to pivot, making it ideal for actuating large chutes, hoppers, or lifting arms in foundries and heavy equipment.
Industrial Gate & Damper Actuation
Provides reliable, high-force actuation for large dampers, gates, and diverters in bulk material processing, where a swinging motion is required.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200TC the Right Cylinder?
Select the SC250 when your application requires forces in the 24544 N class at 0.5 MPa. If your load is lighter, stepping down to a 200 mm bore reduces the push force to 15708 N at the same pressure, potentially saving space and air consumption. For strokes of 300 mm or longer, carefully evaluate side loads on the 50 mm rod; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
To ensure a direct replacement, match five key points: a 250 mm bore, 200 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the absence of a built-in magnet. This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC250X200TC FAQ
At 0.5 MPa, the theoretical push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 44178 N. The absolute maximum force at 1.0 MPa is 5006 kgf.
No. The SC250 is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or lost. For load-holding applications, you must add a pilot-operated check valve or an external mechanical rod lock/brake.
