About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400TC
The AirTAC SC200X400TC is a large-bore double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. With a 400 mm stroke and a robust 40 mm piston rod, this model is built for heavy industrial linear motion tasks requiring high force over a moderate travel distance.
This variant is factory-configured with a TC centre trunnion mount (includes TCM1 bracket, part code F-SC200TC), allowing the cylinder body to pivot as it strokes. The adjustable air cushion at each end, with a 33 mm cushion length, decelerates the massive piston smoothly, protecting the end caps from impact. Ports are PT3/4, and the standard TPU seals provide reliable operation from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400TC Is Used
Heavy Machinery Actuation
Provides the high force needed to tilt or lift heavy implements on agricultural and construction equipment, with the trunnion mount allowing the cylinder to follow an arcing motion path.
Dam Gate & Valve Control
Delivers up to 28274 N at 0.9 MPa to operate large sluice gates or high-torque butterfly valves in water treatment and hydroelectric plants, where pivoting actuation is required.
Mining Conveyor Tensioning
Applies consistent, high-force tension to long conveyor belts in mining and quarrying. The trunnion mount absorbs belt misalignment and dynamic load shifts during operation.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400TC the Right Cylinder?
Select the SC200X400TC when your application needs approximately 15708 N of force at standard plant pressure. If your load requires less force, stepping down to the SC160 bore reduces push force to 10053 N at 0.5 MPa, potentially saving energy and cost. For strokes of 400 mm on a 200 mm bore, side-load management is critical; always guide the load externally or use a guided cylinder if the rod tip experiences any lateral force, as the long unsupported rod can suffer bending stress.
For a direct replacement, match five key attributes: 200 mm bore, 400 mm stroke, PT3/4 port thread, TC centre trunnion mounting (with TCM1 bracket), and the absence of a built-in magnet. This ensures dimensional and functional interchangeability with an existing AirTAC SC200X400TC tie-rod cylinder.

- ✓ 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 SC200X400TC FAQ
At 0.7 MPa operating pressure, the SC200X400TC produces a theoretical push force of 21991 N. The pull force on the retract stroke is slightly lower at 15080 N due to the 40 mm piston rod area.
No. The SC200X400TC is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. The adjustable air cushions only decelerate the piston at stroke end; they do not lock or hold the load. To hold a position without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
