About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400S
The AirTAC SC200X400S is a double-acting single-rod pneumatic cylinder delivering substantial force for heavy industrial automation. With a 200 mm bore and 400 mm stroke, it generates 15708 N of push force at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, clamping, and lifting large assemblies.
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 reliable end-of-stroke detection. The cylinder features a 40 mm diameter piston rod, PT1/2 ports, and a 33 mm adjustable air cushion to decelerate high-inertia loads smoothly. The body length A is 244 mm, giving a total extended length of approximately 644 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400S Is Used
Heavy Pressing & Assembly
Generates up to 28274 N at 0.9 MPa for pressing bearings, riveting large components, or assembling heavy structural frames where consistent force is critical.
Palletising & Material Handling
The 400 mm stroke and high force capacity suit pallet lift stations and heavy-part transfer systems, with the built-in magnet enabling sensor-based sequencing.
Industrial Gate & Damper Actuation
Operates large hopper gates or ventilation dampers in processing plants, using the adjustable cushion to manage the mass of large metal doors without impact damage.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400S the Right Cylinder?
Select the SC200 bore when your application requires push forces above 15708 N at 0.5 MPa; for lighter loads around 6136 N, stepping down to the SC125 bore reduces air consumption and physical size. At 400 mm of stroke, ensure the load is guided externally if any side forces are present—the 40 mm rod, while robust, can experience bending stress under off-axis loads, so linear guides or a guided cylinder configuration are recommended for long-stroke applications.
For a direct replacement, match five key attributes: 200 mm bore, 400 mm stroke, PT1/2 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting style. This SC model is a tie-rod cylinder 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 SC200X400S FAQ
At 0.5 MPa, the cylinder produces 15708 N extending (push) and 15080 N retracting (pull). At 0.7 MPa, push force is 21991 N, and at the maximum operating pressure of 0.9 MPa, it reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet is installed in the piston. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without additional brackets.
