About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1800
The AirTAC SC200X1800 is a large-bore, double-acting tie-rod cylinder built for applications requiring a very long 1800 mm stroke. With a 200 mm bore, it generates a substantial push force of 15708 N at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy industrial actuation.
This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and PT3/4 port threads. The 33 mm adjustable air cushion at each end helps decelerate the high moving mass smoothly. As the 1800 mm stroke exceeds the 1500 mm maximum standard stroke for bore 200, this is a non-standard, made-to-order configuration requiring a careful review of rod buckling and support.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1800 Is Used
Long-Reach Material Pusher
Provides the 1800 mm linear travel needed to push heavy pallets or bulk materials across wide conveyor transfer stations in warehouses.
Heavy Press Ejection
Delivers up to 28274 N of force at 0.9 MPa to eject large formed parts from deep-draw presses or heavy molding machines.
Structural Welding Positioner
Positions large steel structural sections over an 1800 mm span in automated welding cells, maintaining stability with a rigid external guide.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1800 the Right Cylinder?
Select the SC200 when your load requires the 15708 N push force available at 0.5 MPa. For a slightly lower force class in a standard ISO 6430 package, the SC160 bore provides 10053 N at 0.5 MPa. When replacing an existing cylinder, match five key points: 200 mm bore, 1800 mm stroke, PT3/4 port thread, basic mounting (no factory-fitted brackets), and the absence of a barrel magnet.
For this 1800 mm stroke, the 40 mm rod is susceptible to bending under side loads. Always use an external guide system or a self-supporting load carriage to prevent rod bearing damage and ensure seal integrity over the long extension.
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 SC200X1800 FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. For any stroke over 300 mm, and especially at 1800 mm, the piston rod is vulnerable to bending from side loads. An external guide or a self-supporting load carriage is mandatory to protect the rod bearing and seals, and to prevent buckling.
