About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900TC
The AirTAC SC250X900TC is a large-bore double-acting tie-rod cylinder delivering substantial linear force for heavy industrial automation. At 0.5 MPa air pressure, it generates 24544 N pushing and 23562 N pulling, rising to a maximum theoretical force of 5006 kgf at 1.0 MPa. The 250 mm bore houses a 50 mm diameter piston rod with an M42x2 male thread and a 40 mm adjustable air cushion at each end to decelerate high-inertia loads.
This specific model includes a centre trunnion mount (TC), supplied with the TCM1 bracket (F-SC250TC), allowing the cylinder to pivot as it strokes—ideal for swinging or articulating loads. With a 900 mm stroke and a body length of 294 mm, the total extended length is approximately 1194 mm. The standard PT1 inch ports and TPU seals suit filtered air systems operating from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900TC Is Used
Heavy Press & Forming
Provides up to 44178 N of push force at 0.9 MPa for stamping, bending, or die-casting operations where a compact, high-force actuator is needed.
Large Damper & Gate Actuation
The 900 mm stroke and centre trunnion mount allow the cylinder to pivot, making it suitable for operating large hopper gates, diverter chutes, or ventilation dampers.
Structural Testing Rigs
Delivers controlled, repeatable linear force for material testing, structural load simulation, and heavy-duty clamping fixtures in civil engineering labs.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900TC the Right Cylinder?
Choose the SC250 when your application demands forces above 18095 N (the 0.9 MPa push of the SC160). If your load cycle requires less force, stepping down to the SC200 bore reduces air consumption while still providing 15708 N of push at 0.5 MPa. For strokes of 900 mm, always assess side-loading: the 50 mm rod is robust, but any lateral force on the rod end can cause bending stress on the rod bearing. Use an external guide rail or a guided cylinder if off-axis loads are present.
For a direct replacement, match five key specifications: 250 mm bore, 900 mm stroke, PT1 inch pneumatic ports, centre trunnion (TC) mounting with the TCM1 bracket, and the absence of a built-in magnet. This cylinder is not dimensionally interchangeable with ISO 15552 profiles; it is a tie-rod design that is shorter in overall length.
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 SC250X900TC FAQ
At the standard operating pressure of 0.5 MPa, 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 SC250 is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. The adjustable air cushions only decelerate the piston at the end of stroke to reduce impact; they do not lock the rod. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
