About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X900SH
The SC125X900SH is a high-force double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with a built-in magnet (-S) and high-temperature Viton seals (-H). With a 125 mm bore and 900 mm stroke, it generates a push force of 6136 N at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa, making it suitable for demanding linear actuation tasks.
This model operates reliably in environments from 0 to +150 °C thanks to its FKM seal package. The piston rod is a robust 32 mm diameter with an M27x2 knuckle thread, and the adjustable air cushion (28 mm length) decelerates the load smoothly at stroke end. Its PT1/2 ports supply the large air volume needed for fast cycling in this ISO 6430 class cylinder.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X900SH Is Used
Hot Press Actuation
The Viton seals allow this cylinder to operate continuously in high-temperature platen presses, laminators, and thermoforming machines where ambient heat would degrade standard seals.
Heavy Pallet Lifting
With over 11000 N of force at 0.9 MPa, the SC125X900SH can lift and lower heavy pallets or containers on a vertical lift station, with the magnet enabling end-of-stroke position sensing.
Foundry Pusher & Diverters
Ideal for pushing heavy castings or diverting large packages on high-temperature foundry or kiln conveyor lines, where the FKM seals withstand radiant heat and the tie-rod design allows field servicing.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X900SH the Right Cylinder?
Choose the SC125 bore when your application requires between roughly 6,000 and 11,000 N of force at standard shop air pressures. If your load is lighter, stepping down to the SC100 bore (3927 N push at 0.5 MPa) can reduce air consumption and physical size. For heavier loads, the SC160 bore provides 10053 N at the same 0.5 MPa pressure.
At a 900 mm stroke, the 32 mm rod is strong, but any significant side load can cause rod bearing wear and bending. For non-axial loads, guide the rod externally with a linear rail or switch to a guided cylinder. To match this exact model for replacement, confirm five points: 125 mm bore, 900 mm stroke, PT port thread, Viton (FKM) seals for high temperature, and the built-in magnet for barrel-mounted sensors.

- ✓ 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 SC125X900SH FAQ
At 0.5 MPa, 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 reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes. The -S suffix designates a built-in magnet on the piston, allowing you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor grooves for reliable, non-contact position detection.
