About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X400SH
The AirTAC SC250X400SH is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa, scaling up to 44178 N at the maximum operating pressure of 0.9 MPa. With a 400 mm stroke and a robust 50 mm diameter piston rod, it is built for large-scale industrial automation tasks requiring immense force.
This model is equipped with Viton (FKM) seals, designated by the 'H' suffix, extending the operating temperature range from 0 to +150 °C for reliable performance in hot environments. The cylinder features a 40 mm adjustable air cushion at each end to decelerate high-inertia loads, and uses a PT1 inch port for its pneumatic connections.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X400SH Is Used
Heavy Pressing & Clamping
Generates up to 44178 N of force for hydraulic-press alternatives, heavy-duty clamping fixtures, and metal forming operations in high-temperature environments up to 150°C.
Large-Scale Material Handling
Ideal for actuating gates, diverters, and pushers for pallet-sized loads in foundries, steel mills, and cement plants where robust force and heat resistance are critical.
Industrial Process Automation
Powers large mixers, dampers, and valve actuators in chemical and processing industries, with Viton seals ensuring long life against aggressive thermal cycling.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X400SH the Right Cylinder?
Select the SC250 bore when your application requires a push force between 24544 N (at 0.5 MPa) and 44178 N (at 0.9 MPa). If your force requirement is lower, consider stepping down to the SC200 bore, which provides 15708 N of push force at 0.5 MPa. For strokes of 300 mm or more, like this 400 mm model, always evaluate side-loading on the 50 mm rod. An external guide or a guided cylinder is strongly recommended to prevent rod bending and premature bearing wear. To ensure a correct replacement, match five key points: 250 mm bore, 400 mm stroke, PT port thread, basic mounting, and the absence of a 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 SC250X400SH FAQ
At the standard 0.5 MPa operating pressure, the 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 theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC250 tie-rod cylinder or a compatible tie-rod design with matching bore, stroke, PT1 inch ports, and basic mounting.
