About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X140S
The AirTAC SC200X140S is a double-acting tie-rod cylinder with a 200 mm bore and 140 mm stroke, pre-fitted with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. This model produces a substantial push force of 15708 N at 0.5 MPa and reaches 28274 N at the maximum operating pressure of 0.9 MPa, placing it firmly in the heavy-duty industrial class.
Its 40 mm diameter piston rod and PT3/4 port threads handle high flow rates, while the 33 mm adjustable air cushion decelerates the end-of-stroke mass smoothly. The body length A is 244 mm, giving a compact footprint for a bore of this size. Standard TPU seals provide reliable operation from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X140S Is Used
Heavy Press & Clamping
Generates 28274 N of thrust at 0.9 MPa for stamping, riveting, and high-force clamping fixtures in metal fabrication cells.
Palletising & Lift Systems
Provides the muscle for layer palletisers and vertical lifts, moving heavy pallets or engine blocks with the 40 mm rod resisting deflection.
Material Compaction
Drives compaction rams in waste handling or briquetting machines, using the adjustable cushion to manage the high inertial loads at stroke end.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X140S the Right Cylinder?
Choose the SC200 bore when your application requires push forces above 15708 N at standard plant air. If your load is lighter, the SC160 bore delivers 10053 N at 0.5 MPa and may reduce air consumption. For strokes over 300 mm, always assess side-loading on the 40 mm rod—an external guide or a guided cylinder is recommended to prevent rod-bearing bending and premature seal wear.
To replace an existing unit, match five points: 200 mm bore, 140 mm stroke, PT3/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC200 tie-rod 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 SC200X140S FAQ
At 0.7 MPa the SC200 bore generates a theoretical push force of 21991 N. The pull force on the retract stroke is 15080 N at 0.5 MPa, accounting for the 40 mm rod area.
Yes. The -S suffix indicates a built-in magnet is already installed inside the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rod slots without any modification.
