About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100
The SC250X100 is the largest bore in the AirTAC SC tie-rod cylinder family, delivering a substantial 24544 N of push force at just 0.5 MPa. With a 100 mm stroke, this double-acting cylinder is built for heavy-duty industrial applications where extreme force is required in a compact linear movement. The 50 mm diameter piston rod and PT1" port ensure robust, high-flow pneumatic connections.
This model features a 294 mm body length (A dimension) and a 40 mm adjustable air cushion to decelerate the massive 5006 kgf theoretical force at end-of-stroke. Operating on filtered air from 0.15-1.0 MPa, it uses standard TPU seals for a temperature range of -20 to +70 °C. As a genuine AirTAC component, it provides reliable, high-force actuation for demanding environments.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100 Is Used
Heavy-Duty Pressing
Generates up to 44178 N of force at0.9 MPa, ideal for shop presses, stamping fixtures, and heavy clamping operations requiring a short, powerful stroke.
Material Lifting
The 24544 N push force at0.5 MPa makes it suitable for lifting heavy dies, molds, or large components in material handling and assembly stations.
Industrial Automation
Used in large-scale automation for actuating heavy gates, diverters, or chutes in mining, steel, and heavy machinery where robust, high-force linear motion is essential.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100 the Right Cylinder?
Select the SC250X100 when your application requires maximum force in a tie-rod format, such as heavy pressing or lifting. If 24544 N at0.5 MPa exceeds your requirement, step down to the SC200 bore, which provides 15708 N at the same pressure. Conversely, if you need a longer stroke, the SC250 supports standard strokes up to 1500 mm.
For a direct replacement, ensure your existing cylinder matches these five points: 250 mm bore, 100 mm stroke, PT1" port thread, basic (no bracket) mounting, and no built-in magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. For strokes over 300 mm on this bore, an external guide is strongly recommended to protect the 50 mm rod from bending under side loads.
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 SC250X100 FAQ
At the standard operating pressure of0.5 MPa, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of0.9 MPa, the push force increases to 44178 N. The theoretical maximum force at1.0 MPa is 5006 kgf.
No. The SC series is a tie-rod cylinder. While the SC250 is an ISO 6430 class cylinder, it is shorter than an ISO 15552 profile cylinder and is not a drop-in replacement for one. It is a direct replacement only for another AirTAC SC250 tie-rod cylinder with matching stroke, port, and mounting.
