About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X550
The SC250X550 is a large-bore double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. Its 50 mm diameter piston rod and 40 mm adjustable air cushion are built to manage the inertial loads of heavy tooling across a 550 mm stroke.
With a body length A of 294 mm, this cylinder is designed for demanding industrial automation where high thrust is non-negotiable. The PT1" port ensures ample flow for rapid cycling, while the tie-rod construction allows for straightforward field maintenance when required.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X550 Is Used
Heavy Press Tool Actuation
Provides the 24544 N push force at 0.5 MPa needed to drive large forming dies, stamping heads, or clamping fixtures in heavy manufacturing cells.
Bulk Material Gate Control
Operates large diverter gates or hopper discharge doors in aggregate, grain, or recycling facilities, using its high thrust to shear through packed material columns.
Structural Test Rigs
Applies controlled, repeatable loads up to 44178 N in materials testing frames or civil engineering structural component fatigue test systems.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X550 the Right Cylinder?
Select the SC250 bore when your application requires a push force exceeding the 15708 N (at 0.5 MPa) delivered by the SC200. For strokes of 550 mm, always assess side-load conditions; a 50 mm rod is robust, but external guides or a guided cylinder are recommended if the load is not perfectly axial to prevent rod bearing wear and potential bending. When replacing an existing unit, match the 250 mm bore, 550 mm stroke, PT1" port thread, basic mounting configuration, and confirm the magnet option (-S) is not required.
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 SC250X550 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 34361 N and the pull force on the retract stroke is 23562 N. These values assume a static, non-shock load condition.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder of the same bore and stroke, so the mounting dimensions are not interchangeable. It is a direct replacement for another AirTAC SC250 tie-rod cylinder with matching stroke, port, and mounting specifications.
