About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X150
The AirTAC SC250X150 is a large-bore double-acting tie-rod cylinder engineered for heavy industrial force applications. With a 250 mm bore and 150 mm stroke, it generates a substantial 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, clamping, and lifting heavy loads.
This model features a robust 50 mm diameter piston rod with M42x2 threads and a PT1" port for high flow rates. The total extended body length is approximately 444 mm, calculated from the 294 mm body length A plus the 150 mm stroke. The adjustable pneumatic cushion (40 mm length) decelerates the high-inertia piston smoothly at end-of-stroke, protecting the end caps.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X150 Is Used
Heavy Press Tool Actuation
Delivers up to 44178 N of push force at 0.9 MPa for operating large forming dies, punch presses, and bearing insertion tools in heavy manufacturing lines.
Pallet & Container Lifting
Provides the high force capacity needed for lifting and tilting heavy-duty pallets or bulk containers in logistics and material handling stations.
Structural Weld Fixtures
Clamps large steel fabrications and structural components with consistent 24544 N force at 0.5 MPa, ensuring zero movement during automated welding cycles.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X150 the Right Cylinder?
Select the SC250 when your application demands forces exceeding 18000 N, where the next bore down (SC200) provides 15708 N of push at 0.5 MPa. The 50 mm rod on this 250 bore offers excellent rigidity, but for strokes over 300 mm or any side-loading, always use an external guide rail or rod-alignment coupler to prevent bending stress on the rod bearing.
For a drop-in replacement, match five key specifications: 250 mm bore, 150 mm stroke, PT1" port thread, basic mounting (no factory-fitted brackets), and the absence of a built-in magnet. This cylinder is a direct replacement only for another AirTAC SC250X150 tie-rod unit or a mechanically identical copy.
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 SC250X150 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 reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The SC250X150 is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is exhausted or the directional valve centers, the piston will drift. For load-holding safety, you must add a pilot-operated check valve or an external mechanical rod lock.
