About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X300
The AirTAC SC250X300 is a robust double-acting tie-rod cylinder engineered for heavy industrial force requirements, delivering 24544 N of push force 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 300 mm stroke, this cylinder provides a total extended body length of 594 mm, making it a compact yet powerful solution for demanding linear motion tasks.
This model features a 40 mm adjustable air cushion at both ends to decelerate high-inertia loads smoothly, reducing end-of-stroke impact. As a standard-stroke unit within the 1500 mm maximum for the 250 bore, it is readily available. The PT1 inch port thread and M42x2 rod thread ensure secure, high-flow connections for consistent operation in heavy-duty automation.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X300 Is Used
Heavy Press & Forming
Provides up to 44178 N of thrust for stamping, pressing, and metal forming operations where consistent, high-force linear motion is critical.
Large-Scale Material Handling
Powers lifts, tippers, and transfer stations for heavy pallets or bulk materials, leveraging the 24544 N push force at standard 0.5 MPa air pressure.
Structural Testing Rigs
Delivers controlled, repeatable force for load testing of beams, joints, and large components, with adjustable cushioning to protect the test specimen and rig.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X300 the Right Cylinder?
Select the SC250 bore when your application requires a push force exceeding 20000 N at standard plant air pressure; the 250 mm bore offers 24544 N at 0.5 MPa, a significant step up from the SC200's 15708 N. For strokes of 300 mm and above, always assess side-load conditions—the 50 mm rod, while substantial, can experience bending moments under off-axis loads. Use an external guide rail or a guided cylinder configuration to protect the rod bearings and ensure long service life.
For direct replacement, match five key specifications: 250 mm bore, 300 mm stroke, PT port thread, the specific mounting accessory (this basic model uses no bracket), and the magnet option (this unit has no built-in magnet). This ensures a drop-in fit for an existing AirTAC SC tie-rod cylinder.
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 SC250X300 FAQ
At 0.5 MPa, 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 SC250X300 is a double-acting cylinder and will not hold its position if pressure is lost or the valve is centered. The piston can drift or drop under load. For load holding, you must add a pilot-operated check valve, a mechanical lock, or an external rod brake.
