About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650S
The AirTAC SC250X650S is a heavy-duty 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. With a 50 mm diameter piston rod and a 40 mm adjustable air cushion, this ISO 6430 class cylinder is built to decelerate large inertial loads smoothly at the end of its 650 mm stroke.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable, non-contact position sensing. The 294 mm body length A results in a total extended length of approximately 944 mm, making it a compact yet powerful solution for demanding linear motion tasks.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650S Is Used
Heavy Press & Clamping
Generates over 44000 N of clamping force at 0.9 MPa for large-scale assembly presses, riveting stations, and industrial welding fixtures.
Material Handling & Lift
Provides the high push force needed for lifting and transferring heavy pallets, engine blocks, or steel sheets in automated logistics systems.
Construction & Mining Equipment
Suitable for auxiliary actuation on heavy mobile machinery, such as chute gates, screed controls, and compactors, where robust tie-rod construction is essential.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X650S the Right Cylinder?
Select the SC250X650S when your application requires a force class around 24544 N at standard plant pressure. If your load is lighter, stepping down to the SC200 bore reduces push force to 15708 N at 0.5 MPa, which can lower air consumption and cost. For any 650 mm stroke, particularly with a 50 mm rod, ensure the load is guided and side forces are eliminated; long unsupported strokes are susceptible to rod bending and bearing wear. For replacement, match exactly: 250 mm bore, 650 mm stroke, PT port thread, the built-in magnet, and basic mounting.
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 SC250X650S 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 increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel for precise, non-contact end-of-stroke or mid-stroke position detection.
