About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75S
The SC200X75S is a large-bore double-acting pneumatic cylinder delivering a substantial 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa). Its 75 mm stroke, paired with a 40 mm diameter piston rod, provides a compact yet powerful linear actuation solution for heavy-duty industrial tasks.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback. The standard TPU seals offer reliable operation from -20 to +70 °C, with PT1/2 ports and an adjustable pneumatic cushion to decelerate the high inertial loads typical of this force class.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75S Is Used
Heavy Press Tool Actuation
Provides the high force needed for clamping, pressing, and punching operations in metal forming and assembly presses, with sensor confirmation of tool position.
Large Gate & Damper Control
Operates heavy bulk material gates or air dampers in silos and material handling lines, where the 15708 N push force easily overcomes material weight and friction.
Palletiser Lift & Transfer
Drives vertical lift or horizontal transfer carriages in palletising systems, with the magnetic piston enabling precise sequence control via barrel-mounted sensors.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X75S the Right Cylinder?
For applications requiring slightly less force, the 160 mm bore SC160 series provides 10053 N at 0.5 MPa. The SC200X75S is a standard-stroke model, well within the 1500 mm maximum for this bore. When replacing an existing cylinder, match five key points: 200 mm bore, 75 mm stroke, PT port thread, the built-in magnet sensor capability, and the basic tie-rod mounting footprint. Always confirm the body length A of 244 mm plus stroke fits your machine envelope.
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 SC200X75S 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. The theoretical maximum force at 1.0 MPa is 3204 kgf.
Yes. The -S suffix in SC200X75S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without additional brackets.
