About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X290SH
The AirTAC SC125X290SH is a double-acting single-rod pneumatic cylinder with a 125 mm bore and 290 mm stroke, part of the tie-rod SC series. It generates a push force of 6136 N at 0.5 MPa and 11045 N at the maximum operating pressure of 0.9 MPa, driven by a 32 mm diameter piston rod with an M27x2 thread.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors, and features high-temperature Viton (FKM) seals (-H suffix), extending the operating range to 0–150 °C. With a 28 mm adjustable air cushion, a body length of 203 mm, and PT1/2 ports, it is suited for demanding industrial automation tasks where heat resistance and position sensing are critical.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X290SH Is Used
Hot Press & Molding
The Viton seals and high 11045 N force at 0.9 MPa make this cylinder ideal for clamping and ejecting parts in heated presses, thermoforming, and rubber molding machines operating up to 150 °C.
Heavy Material Handling
With 6136 N of push force at 0.5 MPa and a 290 mm stroke, it reliably lifts, pushes, or positions heavy bins and pallets on conveyors in foundries or heat-treatment lines.
Sensor-Controlled Automation
The built-in magnet allows CMSG/DMSG sensors to confirm end-of-stroke position, enabling precise, closed-loop control of gates, diverters, or clamping sequences in automated machinery.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X290SH the Right Cylinder?
Select the SC125 bore when your application requires a push force around 6136 N at standard 0.5 MPa supply. If you need less force, the SC100 bore provides 3927 N at the same pressure; for more force, step up to the SC160 bore at 10053 N. This 290 mm stroke is within the standard range for this bore, which supports up to 1500 mm.
For a direct replacement, match five key points: 125 mm bore, 290 mm stroke, PT1/2 port thread, the built-in magnet for sensors, and the Viton seal material. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. For strokes over 300 mm, always check side-load conditions and consider an external guide to protect the rod bearing from bending.
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 AIRTAC SC125-160 Standard Cylinder SC125X290SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 cylinder of the same bore and stroke, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with matching stroke, port thread, magnet option, and Viton seals.
