About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X800S
The AirTAC SC250X800S is a large-bore 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 an 800 mm stroke and a 50 mm diameter piston rod, it is built for heavy industrial linear tasks requiring substantial power and a long working reach.
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 non-contact position sensing. The body length A is 294 mm, the total extended length is approximately 1094 mm, and the adjustable pneumatic cushion (40 mm) decelerates the piston smoothly at stroke ends. Operating on filtered air from 0.15 to 1.0 MPa, it uses standard PT ports (1 inch) and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X800S Is Used
Heavy Press & Forming
Delivers up to 44178 N of thrust for stamping, bending, or compression jigs in metal forming and composite molding operations.
Pallet & Bulk Handling
Pushes or lifts heavy pallets and bulk containers on conveyor lines, with sensor feedback confirming full extension and retraction.
Structural Testing Rigs
Applies controlled, high-force linear loads for material testing, structural component fatigue tests, and civil engineering experiments.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X800S the Right Cylinder?
Select the SC250 bore for applications demanding over 24000 N of force at standard plant pressure. If your load requires less force, stepping down to the SC200 bore (15708 N push at 0.5 MPa) can reduce air consumption and physical footprint. For an 800 mm stroke, ensure the rod is not subjected to significant side loading; long, unsupported strokes on a 50 mm rod can experience bending moments. Use an external guide rail or rod-alignment coupler to protect the rod bearing and seals.
For a direct replacement, match five key attributes: 250 mm bore, 800 mm stroke, 1-inch PT port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This cylinder is not dimensionally interchangeable with ISO 15552 profiles; it is an AirTAC SC tie-rod design, which is shorter in overall length.
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 SC250X800S FAQ
At 0.5 MPa (approx. 5 bar), 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 force at 1.0 MPa is 5006 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston. You can clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel to detect piston position without additional brackets.
