About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1150
The AirTAC SC200X1150 is a double-acting tie-rod cylinder engineered for heavy linear force applications. With a 200 mm bore and 1150 mm stroke, it generates a substantial 15708 N of push force at 0.5 MPa, rising to 28274 N at the maximum operating pressure of 0.9 MPa.
This model features a robust 40 mm diameter piston rod with M36x2 male threads and PT3/4 port connections. The total extended body length is approximately 1394 mm, combining the 244 mm base body length with the 1150 mm working stroke. An adjustable pneumatic cushion, with a 33 mm cushion length, decelerates the piston at both ends to reduce end-of-stroke impact.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1150 Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces required for large-scale metal forming, stamping, or composite molding presses, ensuring consistent pressure throughout the 1150 mm stroke.
Large-Scale Material Handling
Drives heavy-duty pushers or lifters in sawmills, steel warehouses, or recycling plants, moving large pallets or bulk materials with the cylinder's 28 kN peak thrust.
Industrial Damper & Gate Control
Operates large ventilation dampers, flue gates, or hopper discharge doors in heavy industry, where the long 1150 mm stroke is needed for full-range motion and reliable sealing force.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1150 the Right Cylinder?
Select the SC200 bore when your application requires between 15708 N and 28274 N of push force. For a lighter force class, consider stepping down to the SC160 bore, which provides 10053 N of push at 0.5 MPa. For a higher force requirement, the SC250 bore delivers 24544 N at the same pressure.
For this 1150 mm stroke, side loading on the rod must be carefully managed to prevent bearing wear and rod bending. It is essential to guide the load externally with a linear rail or rod guide, as the SC cylinder's rod bearing is designed for axial thrust, not lateral forces. When replacing this unit, match five critical points: the 200 mm bore, 1150 mm stroke, PT3/4 port thread, basic mounting configuration, and the absence of a magnetic piston.
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 SC200X1150 FAQ
At 0.7 MPa operating pressure, the SC200X1150 generates a push force of 21991 N and a pull force of 15080 N on the retract stroke. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The SC200 is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston can drift. To hold a load safely in a power-off state, you must add an external rod lock or a pilot-operated check valve.
