About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600TC
The SC250X600TC is a large-bore double-acting pneumatic cylinder delivering substantial push force of 24544 N at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With a 50 mm diameter piston rod and a 600 mm stroke, this model is built for heavy-duty industrial tasks requiring high force over a moderate travel distance.
This configuration includes a centre trunnion mount (TC), supplied with the TCM1 bracket (F-SC250TC), allowing the cylinder to pivot during operation. The tie-rod construction houses a 40 mm adjustable air cushion at each end to decelerate the massive piston, and the PT1 inch port supplies the necessary flow for the 30-500 mm/s speed range typical of this ISO 6430 class cylinder.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600TC Is Used
Heavy Press Tool Actuation
Provides up to 44178 N of force for clamping and forming in large stamping presses, where the centre trunnion mount allows the cylinder body to align with the press mechanism.
Damper and Valve Control
Operates large industrial dampers and high-torque butterfly valves, using the pivoting TC mount to follow the valve stem's arc and the high force to overcome system back-pressure.
Material Handling Tippers
Powers the tilt mechanism on heavy-duty bin tippers and hoppers, with the trunnion mount absorbing the pivoting motion and the 50 mm rod handling the bending moment from the load.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600TC the Right Cylinder?
Select the SC250 when your application demands forces in the 24000-44000 N range. For a step down in force, the SC200 bore provides 15708 N at 0.5 MPa, while this 250 mm bore is the largest in the SC family. The 600 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
To ensure a direct replacement, match five key points: the 250 mm bore, 600 mm stroke, PT1 inch port thread, centre trunnion (TC) mounting, and the absence of a magnet. For this 600 mm stroke, ensure the load is guided externally if side forces are present; the 50 mm rod is robust, but long unsupported strokes under side load can cause rod bearing wear and bending.
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 SC250X600TC 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 reaches 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
No, the SC250X600TC is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. For load holding without live pressure, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve in the circuit.
