About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X90S
The SC200X90S is a robust double-acting tie-rod cylinder delivering a substantial 15708 N of push force at 0.5 MPa (28274 N at the 0.9 MPa maximum operating pressure). With a 200 mm bore and 90 mm stroke, this model features a 40 mm diameter piston rod and an adjustable air cushion length of 33 mm for effective end-of-stroke deceleration.
This variant 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 detection. It is a genuine AirTAC SC series unit, factory-equipped with PT ports and standard TPU seals for reliable operation from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X90S Is Used
Heavy Press Tool Actuation
Generates over 28 kN of force at 0.9 MPa for stamping, riveting, and heavy clamping operations in metal fabrication cells.
Large Valve & Damper Control
Provides the high thrust needed to operate large industrial butterfly valves or flue gas dampers, with sensor feedback confirming open/closed status.
Palletizer Ram Displacement
Pushes heavy pallets or slip sheets into position on automated packaging lines, where the magnetic piston enables precise end-of-stroke sensing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X90S the Right Cylinder?
For applications needing slightly less force, the 160 mm bore SC160 series provides 10053 N at 0.5 MPa, while the 250 mm bore SC250 steps up to 24544 N. Ensure a proper replacement match by verifying all five points: 200 mm bore, 90 mm stroke, PT port thread, the built-in magnet option, and the basic (no bracket) mounting configuration. The SC series 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 SC200X90S 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 reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
Yes. The -S suffix in the model code SC200X90S indicates a built-in magnet on the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel to detect piston position without any additional brackets.
