About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X270
The SC200X270 is a large-bore double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa, rising to 28274 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 33 mm adjustable air cushion, this 200 mm bore actuator is built to manage heavy loads through a 270 mm stroke.
Its body length A measures 244 mm, giving a total extended length of approximately 514 mm. The PT3/4 port and M36x2 rod thread provide robust connections for high-flow pneumatic circuits. This model is supplied with standard TPU seals for a -20 to +70 °C operating range and PT thread ports.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X270 Is Used
Heavy Pallet Lifting
Provides the high force needed for lifting and stacking loaded pallets in automated warehouse systems, using its 15708 N push at standard line pressure.
Large Press Tool Actuation
Drives clamping and forming tools in heavy manufacturing presses, where the 28274 N maximum force at 0.9 MPa securely holds workpieces.
Bulk Material Gate Control
Operates heavy diverter gates on conveyors for mining or aggregate, leveraging the robust 40 mm rod to withstand high-cycle, dusty environments.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X270 the Right Cylinder?
For applications requiring slightly less force, the 160 mm bore SC160 series provides 10053 N at 0.5 MPa. If your load demands exceed the 15708 N available here, stepping up to the 250 mm bore SC250 series offers 24544 N at the same pressure. Always ensure the mounting and rod alignment prevent side loading, especially on a 270 mm stroke.
When replacing an existing cylinder, match five key points: 200 mm bore, 270 mm stroke, PT port thread, basic (no bracket) mounting, and the absence of a magnet. This SC200X270 is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC200X270 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 at 1.0 MPa is 3204 kgf.
No. The SC200X270 is a double-acting cylinder and will drift or drop if pressure is lost or the valve is centered. It relies on live air pressure for positioning. For load holding without pressure, you must add an external rod brake or a pilot-operated check valve.
