About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600
The SC250X600 is a heavy-duty double-acting pneumatic cylinder from the AirTAC SC tie-rod series, engineered for applications demanding extreme force. With a 250 mm bore and 600 mm stroke, this model 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 large-scale pressing, lifting, and heavy industrial automation tasks.
This cylinder features a robust 50 mm diameter piston rod with an M42x2 male thread and a 1-inch PT port for high flow. The total extended body length is approximately 894 mm (294 mm body length A + 600 mm stroke). It includes an adjustable air cushion with a 40 mm cushion length to effectively decelerate high-inertia loads at the end of the stroke, protecting the end cap from impact damage.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600 Is Used
Heavy Press Tool Actuation
Provides the high force (up to 44178 N at 0.9 MPa) needed to operate large clamping fixtures, punch presses, and heavy-duty forming tools in metal fabrication lines.
Pallet and Bulk Material Lifting
Ideal for scissor lifts and heavy-duty vertical lift stations in warehouses, using its 24544 N push force at 0.5 MPa to raise pallets of bulk goods or heavy machinery components.
Log and Timber Handling
Used in sawmills for log turners and stops, where the large bore and robust 50 mm rod withstand the harsh, high-impact environment of moving and positioning heavy timber on conveyors.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600 the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the SC200 bore, which provides 15708 N of push force at 0.5 MPa. If your load demands exceed the SC250's capacity, a larger bore or a tandem configuration may be necessary. This 600 mm stroke model is within the standard stroke range for the 250 mm bore (max 1500 mm).
At this stroke length, the 50 mm rod is robust, but any significant side loading must be managed with an external guide rail or rod support to prevent bending stress on the rod bearing and seal. To ensure a correct replacement, match these five points: 250 mm bore, 600 mm stroke, 1-inch PT port thread, basic mounting (no factory-fitted bracket), and the absence of a built-in 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 SC250X600 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 adjustable air cushion is designed only to decelerate the piston near the end of its stroke to reduce impact. It does not hold or lock the load. If you need to stop and hold a load mid-stroke or in the event of air pressure loss, you must use an external mechanical brake, a rod lock, or a pilot-operated check valve in the circuit.
