About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X950S
The SC200X950S is a double-acting single-rod pneumatic cylinder delivering 15 708 N push force at 0.5 MPa (28 274 N at the 0.9 MPa maximum operating pressure). Its 40 mm diameter rod and 33 mm adjustable air cushion make it well-suited for heavy linear actuation over a 950 mm stroke.
The built-in magnet (-S suffix) allows CMSG/DMSG/EMSG reed or solid-state sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. With a PT1/2 port, TPU seals rated for -20 to +70 °C, and a body length A of 244 mm, this genuine AirTAC cylinder is engineered for demanding industrial automation.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X950S Is Used
Pallet & Container Handling
The 15 708 N push force at 0.5 MPa drives heavy pallet lifts, container stops, and transfer stations. The 950 mm stroke covers wide conveyor sections, and the built-in magnet enables end-of-stroke verification.
Large Press & Clamping Fixtures
With 28 274 N of thrust at 0.9 MPa, this cylinder applies high clamping pressure in woodworking, metal-forming, or composite-bonding presses. The adjustable cushion protects tooling at the end of the 950 mm travel.
Heavy-Duty Gate & Damper Actuation
Operates large hopper gates, diverter chutes, or ventilation dampers. The tie-rod construction handles harsh environments, and the magnet-equipped barrel simplifies sensor integration for open/closed confirmation.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X950S the Right Cylinder?
Choose the SC200 bore when your application needs roughly 15 700 N push at 0.5 MPa; if you can accept about 10 000 N, stepping down to the SC160 (push 10 053 N at 0.5 MPa) may reduce envelope size and air consumption. For strokes of 300 mm or more, always evaluate side-load and rod-bearing bending — an unsupported 950 mm stroke can amplify deflection under off-axis forces; use an external guide or a guided-cylinder assembly when side load is present.
When replacing an existing unit, match five points: 200 mm bore, 950 mm stroke, PT port thread, the built-in magnet (-S) for sensor mounting, and any mounting accessory (this model is basic, no bracket). The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC of the same configuration.
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 SC200X950S FAQ
At 0.5 MPa the theoretical push force is 15 708 N and pull force is 15 080 N. At the maximum operating pressure of 0.9 MPa, push reaches 28 274 N. The absolute maximum theoretical force at 1.0 MPa is 3204 kgf (31 420 N push).
Yes. The -S suffix indicates a built-in magnet on the piston, so AirTAC CMSG, DMSG, or EMSG sensors can be clamped onto the tie-rod barrel for reliable position detection without external brackets or flags.
