About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X250S
The AirTAC SC250X250S is a heavy-duty double-acting tie-rod cylinder engineered for applications demanding extreme force. At 0.5 MPa air pressure, it generates 24544 N of push force and 23562 N on the pull stroke, driven by a robust 50 mm diameter piston rod. The 250 mm stroke is well within the standard range for this bore, and the cylinder body measures 294 mm (dimension A), giving a total extended length of approximately 544 mm.
This model includes the -S suffix, indicating a built-in magnet embedded in the piston. This allows for direct, non-contact position sensing by clamping AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel. The standard TPU seals provide reliable operation in standard temperatures from -20 to +70 °C, with PT1 inch ports for air supply.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X250S Is Used
Heavy Industrial Presses
Provides the immense clamping and pressing force needed for forming, stamping, and compacting operations in heavy manufacturing. The 24544 N push force at 0.5 MPa handles the toughest materials.
Large-Scale Material Handling
Operates heavy-duty lift tables, tippers, and transfer carriages in steel mills, foundries, and large warehouses. The built-in magnet enables precise end-of-stroke confirmation for automated sequences.
Structural Testing Rigs
Applies controlled, high-force loads for testing the integrity of structural components, beams, and large assemblies. Sensor feedback from the -S magnet ensures accurate cycle counting and position verification.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X250S the Right Cylinder?
For applications needing the highest force in the SC series, the 250 mm bore is the ultimate choice, offering 24544 N at 0.5 MPa. If your load requires less force, consider stepping down to the 200 mm bore, which provides 15708 N at the same pressure, allowing for a smaller, lighter installation. For strokes of 250 mm and above on this large bore, ensure the load is guided and perfectly aligned; the 50 mm rod is strong, but side loads can cause premature bearing wear and seal failure. When replacing an existing cylinder, match five critical points: 250 mm bore, 250 mm stroke, PT1 inch port thread, the built-in magnet option (-S), and the basic (footless) mounting configuration.
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 SC250X250S FAQ
At 0.7 MPa operating pressure, the theoretical push force is 34361 N, and the pull force is 23562 N. The maximum force at the 0.9 MPa operating limit is 44178 N push. Always design with a safety factor for dynamic loads.
Yes. The 'S' in the model code SC250X250S signifies a built-in magnetic piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the cylinder's tie-rod barrel to detect piston position without external brackets or flags.
