About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300
The SC200X300 is a large-bore double-acting tie-rod cylinder delivering 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. Its 300 mm stroke, paired with a robust 40 mm diameter piston rod and M36x2 rod thread, makes it well-suited for heavy-duty linear actuation tasks requiring significant force over a moderate distance.
This model features a body length A of 244 mm, resulting in a total extended length of approximately 544 mm. The adjustable pneumatic cushion, with a 33 mm cushion length, effectively decelerates the high-inertia piston at the end of each stroke. With PT3/4 ports and standard TPU seals, it operates reliably in a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300 Is Used
Heavy Machinery Actuation
Provides the high force needed for lifting or tilting heavy components in agricultural and construction equipment, such as a harvester header or a bulldozer blade angle control.
Industrial Press & Clamping
Ideal for large-scale clamping fixtures and material forming presses where a consistent and powerful force of over 15,000 N is required to hold or shape workpieces.
Waste Compaction Systems
Used in recycling balers and waste compactors to drive the main compaction plate, efficiently densifying materials with its 28274 N maximum thrust at 0.9 MPa.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300 the Right Cylinder?
Select the SC200 bore when your application requires a push force between roughly 3927 N (the SC100's output at 0.5 MPa) and 15708 N. If your load demands more force, stepping up to the SC250 bore provides 24544 N at the same pressure. For strokes of 300 mm or more, always evaluate side-loading conditions; the 40 mm rod is strong, but an external guide or a guided cylinder is recommended to protect the rod bearing from bending moments caused by off-centre loads.
To ensure a correct replacement, match five key specifications: a 200 mm bore, a 300 mm stroke, PT3/4 port thread, the specific mounting accessory (this basic model has none), and the absence of a built-in magnet. This cylinder is a tie-rod design and is dimensionally shorter than a standard ISO 15552 profile cylinder, so it is not a direct drop-in replacement for that type.
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 SC200X300 FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. As a standard double-acting cylinder, the SC200X300 will not hold its position if air pressure is lost, exhausted, or the control valve is centered. The piston can drift or the load can drop. The adjustable air cushion only decelerates the piston at the stroke end to reduce impact and is not a locking or holding device. For load holding, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve.
