About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X350S
The SC250X350S is a large-bore double-acting pneumatic cylinder delivering 24544 N of push force at 0.5 MPa, rising to 44178 N at the maximum operating pressure of 0.9 MPa. With a 350 mm stroke and a 50 mm diameter piston rod, it is built for heavy industrial linear motion tasks where substantial thrust is required.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be mounted directly on the tie-rod barrel for reliable end-of-stroke position sensing. The adjustable air cushion (40 mm) decelerates the piston smoothly at each end, protecting the end caps during high-energy cycles. As a genuine AirTAC SC tie-rod cylinder, it provides a robust, serviceable design for demanding factory environments.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X350S Is Used
Heavy Press & Clamping
Generates up to 44178 N of force at 0.9 MPa for large-scale pressing, riveting, and clamping fixtures in steel fabrication and assembly lines.
Material Handling Gates
Powers diverter gates and heavy part stops on wide conveyor systems, with the built-in magnet providing confirmation of gate position via CMSG sensors.
Structural Testing Rigs
Applies controlled, repeatable linear loads in structural test frames, where the adjustable cushion protects the cylinder and test specimen from impact damage.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X350S the Right Cylinder?
Select the SC250X350S when your application needs around 24544 N of push force at standard plant pressure. If your load requires less force, stepping down to a 200 mm bore reduces push force to 15708 N at 0.5 MPa, potentially saving space and air consumption. For strokes of 350 mm, ensure side loads are minimal; the 50 mm rod handles substantial axial force, but any lateral force at full extension requires an external guide rail or a guided cylinder to prevent rod bearing damage and bending.
When replacing an existing cylinder, match these five points exactly: 250 mm bore, 350 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This ensures drop-in interchangeability with another AirTAC SC250 cylinder of the same specification.
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 SC250X350S 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, push force reaches 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code SC250X350S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel for non-contact position sensing.
