About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X750SH
The SC125X750SH is a double-acting single-rod pneumatic cylinder delivering up to 11045 N of push force at 0.9 MPa, placing it firmly in the heavy-duty industrial class. With a 125 mm bore and a 750 mm stroke, this model features a 32 mm piston rod, PT1/2 ports, and a 28 mm adjustable air cushion to decelerate high-inertia loads smoothly.
This variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and high-temperature Viton (FKM) seals (-H) that shift the operating range to 0–150 °C. It is an ISO 6430 class tie-rod cylinder, ideal for hot environments where standard seals would degrade.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X750SH Is Used
High-Temperature Foundry Actuation
The Viton seals withstand ambient temperatures up to 150 °C, making this cylinder suitable for clamping molds or operating gates in foundries and heat-treatment facilities.
Heavy Press and Forming
With 11045 N of push force at 0.9 MPa, this 125 mm bore cylinder provides the muscle for medium-duty stamping, pressing, and forming operations in metalworking.
Sensor-Monitored Material Handling
The built-in magnet allows CMSG/DMSG sensors to confirm end-of-stroke position, critical for automated palletizing or large-part transfer lines requiring piston verification.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X750SH the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 100 mm bore (7068 N at 0.9 MPa). If you need more force, the 160 mm bore provides 18095 N. At a 750 mm stroke, the 32 mm rod is robust, but always check for side loads—long strokes can create bending moments on the rod bearing. Use an external guide or a guided cylinder if the load is not perfectly axial.
To ensure a correct replacement, match these five points: 125 mm bore, 750 mm stroke, PT1/2 port thread, the built-in magnet (-S) for sensor compatibility, and the Viton seal (-H) for high-temperature operation. This is an AirTAC SC tie-rod cylinder, not an ISO 15552 profile cylinder, so dimensional interchangeability is limited to other SC series units.
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 SC125X750SH FAQ
At the standard 0.7 MPa operating pressure, the push force is 8590 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125X750SH is a double-acting cylinder and will not hold its position or a load if air pressure is lost, exhausted, or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of stroke; it is not a locking or braking device. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
