About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X110S
The SC250X110S 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 0.9 MPa. With a 250 mm bore and 110 mm stroke, it is built for applications requiring immense clamping, pressing, or lifting power within a compact stroke length. The 50 mm diameter piston rod and 40 mm adjustable air cushion at each end ensure robust, controlled deceleration of high inertial loads.
This model includes a built-in magnet (-S suffix), allowing easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for contactless position sensing. Operating on filtered air from 0.15 to 1.0 MPa, the SC250X110S uses standard PT ports and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X110S Is Used
Heavy Industrial Presses
Provides the extreme clamping force needed for hydraulic-press alternatives in assembly, forming, and stamping operations, with sensor-ready position feedback.
Large-Scale Material Handling
Ideal for lifting and positioning heavy pallets or structural steel members, where the 24544 N push force at 0.5 MPa ensures safe, controlled movement.
Automated Welding Fixtures
Secures large weldments with repeatable, high force. The built-in magnet allows sensors to confirm clamp position before the robot cycle starts, enhancing safety.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X110S the Right Cylinder?
Select the SC250 for force requirements exceeding the SC200's 15708 N push at 0.5 MPa. The 250 mm bore provides a significant step up in power for the most demanding tasks. For strokes over 300 mm, carefully evaluate side loads; an unsupported 50 mm rod can experience bending moments. Use external linear guides or a guided cylinder configuration to protect the rod bearings and ensure long service life.
To replace an existing cylinder, match these five points exactly: 250 mm bore, 110 mm stroke, PT (1 inch) port thread, the built-in magnet for sensor compatibility (-S suffix), and the basic mounting style. This ensures a direct, drop-in fit for another AirTAC SC250 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 SC250X110S FAQ
At 0.5 MPa, it delivers 24544 N pushing and 23562 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code SC250X110S indicates a built-in magnet in the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the cylinder barrel for non-contact end-of-stroke or mid-stroke position sensing.
