About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650TC
The AirTAC SC250X650TC is a large-bore double-acting pneumatic cylinder delivering substantial linear force for heavy-duty industrial applications. With a 250 mm bore, it generates 24544 N of push force at 0.5 MPa and up to 44178 N at 0.9 MPa, driven by a robust 50 mm diameter piston rod.
This model features a 650 mm stroke with adjustable pneumatic cushioning (40 mm cushion length) for smooth end-of-stroke deceleration. The integrated centre trunnion mount (TC, supplied with TCM1 bracket F-SC250TCM1) allows the cylinder to pivot, accommodating swinging loads. Operating on filtered air from 0.15-1.0 MPa, it uses standard PT ports (PT1") and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650TC Is Used
Heavy Machinery Actuation
Provides the high force needed for lifting, tilting, or positioning heavy attachments on construction and agricultural equipment, with the trunnion mount allowing free pivot.
Large-Scale Material Handling
Operates large gates, diverters, or pushers in bulk material handling systems, reliably moving heavy loads with 24544 N of force at standard line pressure.
Industrial Press & Clamp
Delivers up to 44178 N of clamping force at 0.9 MPa for heavy-duty pressing, forming, or holding operations in manufacturing cells.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650TC the Right Cylinder?
Select the SC250 when your application requires force in the 24544 N (push at 0.5 MPa) class. For a step down in force, the SC200 bore provides 15708 N push at the same pressure, while the SC250 remains the largest standard SC single-rod option. Always match bore, 650 mm stroke, PT1" port thread, TC centre trunnion mounting, and the absence of a magnet when replacing an existing unit.
For this 650 mm stroke, ensure the load is guided externally if significant side forces are present. Long unsupported strokes on a single-rod cylinder can impose bending moments on the rod bearing; use external guide rails or a guided cylinder configuration to protect the rod and seals from premature wear.
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 SC250X650TC FAQ
At the standard operating pressure of 0.5 MPa, the cylinder produces 24544 N pushing force and 23562 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No, the SC250 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift. For load holding, you must add an external rod lock, brake, or a pilot-operated check valve in the circuit.
