About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X175TC
The AirTAC SC250X175TC is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa, scaling up to a formidable 44178 N at the maximum operating pressure of 0.9 MPa. With a 175 mm stroke and a 50 mm diameter piston rod, this model is built for large-scale industrial automation tasks requiring immense power in a compact linear footprint.
This variant comes factory-equipped with a TC centre trunnion mount, including the TCM1 bracket, allowing the cylinder body to pivot for swinging loads. The body length A is 294 mm, and the adjustable pneumatic cushion (40 mm length) decelerates the high inertial mass smoothly, protecting the end caps during each cycle.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X175TC Is Used
Heavy Machinery Steering
Provides the high-force pivoting actuation needed for articulated steering systems on large agricultural or construction vehicles, where the trunnion mount absorbs misalignment.
Sluice Gate Actuation
Operates heavy sluice gates or penstocks in water management facilities, using 24544 N of force at 0.5 MPa to reliably lift or lower large panels against water pressure.
Large Press Tooling
Delivers the clamping force for massive industrial presses in wood or metal forming, with the TC mount allowing the cylinder to swing clear for part loading and unloading.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X175TC the Right Cylinder?
Select the SC250 when your application demands a push force class above 18095 N at 0.9 MPa, where the next smaller SC160 bore (18095 N) falls short. For purely linear thrust without pivoting, the basic or foot-mounted SC250 variants reduce mounting complexity. At a 175 mm stroke, the 50 mm rod is well-supported, but for strokes exceeding 300 mm on this bore, always assess side loads and consider an external guide system to prevent rod bearing wear and bending. To replace an existing unit, match these five points exactly: 250 mm bore, 175 mm stroke, PT port thread, TC centre trunnion mount, and the absence of a built-in magnet.
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 SC250X175TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf, though operating above 1.0 MPa is not permitted.
No. The SC250X175TC is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of the stroke; it is not a locking or holding brake. For load-holding applications, you must add an external mechanical lock, rod brake, or a pilot-operated check valve.
