About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25S
The AirTAC SC200X25S is a large-bore double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa (28274 N at the 0.9 MPa maximum operating pressure). Its 40 mm diameter piston rod and 33 mm adjustable air cushion handle high-energy end-of-stroke deceleration, making it suitable for short, high-force clamping or pressing strokes.
This model includes a built-in magnet (suffix -S), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for non-contact position sensing. The standard PT1/2 port and TPU seals cover a -20 to +70 °C operating range, with a total extended length of approximately 269 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25S Is Used
Heavy-Duty Clamping
Generates up to 28274 N of force for securely holding large weldments, castings, or structural assemblies during machining or fabrication.
Short-Stroke Pressing
The 25 mm stroke and high force output are ideal for bearing insertion, riveting, or staking operations where a compact, powerful cylinder is needed.
Material Stop & Positioning
With a built-in magnet for sensor feedback, this cylinder reliably acts as a heavy-duty end-stop or diverter on conveyor lines handling pallets or large packages.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25S the Right Cylinder?
Choose the SC200 bore when your application requires push forces in the 15708 N (at 0.5 MPa) to 28274 N (at 0.9 MPa) range. If your force requirement is lower, stepping down to the SC160 bore reduces push force to 10053 N at 0.5 MPa, saving space and air consumption. For higher forces, the SC250 bore provides 24544 N at the same pressure.
For a direct replacement, match these five points: 200 mm bore, 25 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration. This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC200X25S FAQ
At the standard 0.5 MPa operating pressure, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N.
Yes. The -S suffix in the model code SC200X25S indicates a built-in magnet is installed on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel for end-of-stroke or mid-stroke position detection.
