About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700
The AirTAC SC250X700 is a heavy-duty double-acting tie-rod cylinder delivering a substantial 24544 N of push force at just 0.5 MPa, rising to 44178 N at the maximum operating pressure of 0.9 MPa. With a 250 mm bore and a 50 mm diameter piston rod, this cylinder is built for the most demanding industrial linear motion tasks, providing a theoretical maximum force of 5006 kgf at 1.0 MPa.
This model features a 700 mm stroke, well within the 1500 mm maximum standard stroke for the 250 mm bore. The cylinder body has a length (A) of 294 mm, and its adjustable pneumatic cushion (40 mm length) effectively decelerates the high-inertia piston assembly at the end of travel, reducing impact and noise. The standard port is PT1".

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700 Is Used
Heavy Press & Forming
Provides up to 44 kN of force at 0.9 MPa for stamping, pressing, and metal forming operations in heavy manufacturing lines.
Bulk Material Handling
Operates large gates, diverters, and chutes in mining, aggregate, and agricultural bulk handling systems, moving high-mass loads with reliable pneumatic power.
Structural Testing Rigs
Applies controlled, high-force linear loads for static and dynamic testing of large structural components, beams, and civil engineering materials.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700 the Right Cylinder?
Select the SC250X700 when your application requires a force class around 24.5 kN at standard plant pressure. If a slightly lower force suffices, stepping down to the SC200 bore (15708 N push at 0.5 MPa) can reduce physical size and air consumption. For a 700 mm stroke, ensure the load is guided and axial; long strokes on a single rod cylinder are susceptible to side-load bending. Always use an external guide or rod support to protect the rod bearing and seal. For a direct replacement, match the 250 mm bore, 700 mm stroke, PT1" 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 SC250X700 FAQ
At 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 reaches 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
No. The SC250X700 is a double-acting cylinder and will not hold its position when air pressure is exhausted or the directional valve is centered. For load holding, you must add a pilot-operated check valve or an external mechanical rod brake.
