About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700TC
The AirTAC SC250X700TC is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at just 0.5 MPa (34361 N at 0.7 MPa), placing it in the 5000 kgf class for demanding industrial actuation. Its 700 mm stroke is paired with a 50 mm diameter piston rod and a generous 40 mm adjustable air cushion, providing smooth deceleration of large inertial loads.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC250TC), allowing the cylinder to pivot and self-align in swinging applications. The standard PT ports and TPU seals suit ambient temperatures from -20 to +70 °C, while the ISO 6430 class tie-rod construction ensures robust, serviceable performance.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700TC Is Used
Heavy Machinery Actuation
Powers large levers, gates, and lifting arms on construction and agricultural equipment with 24544 N of force at 0.5 MPa.
Dam & Floodgate Control
Operates large sluice gates and water control valves, where the 40 mm cushion absorbs the energy of massive moving components.
Large Press & Forming
Provides the high clamping and pressing forces needed in large-scale metal forming, composite moulding, and waste compactors.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X700TC the Right Cylinder?
For applications requiring less force, stepping down to a 200 mm bore reduces push force to 15708 N at 0.5 MPa, while the 250 mm bore provides maximum thrust in the SC family. At 700 mm stroke, ensure the rod is not subjected to direct side loads; use an external linear guide or rod support to prevent bending of the 50 mm rod under compression. For replacement, match exactly: 250 mm bore, 700 mm stroke, PT port thread, TC centre trunnion mounting, and no 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 SC250X700TC FAQ
