About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400S
The AirTAC SC125X1400S is a double-acting tie-rod cylinder with a 125 mm bore and a 1400 mm stroke, pre-equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. Operating on filtered air at 0.15–1.0 MPa, it generates a substantial push force of 6136 N at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa, placing it firmly in the ISO 6430 class for heavy-duty applications.
This model features a 32 mm piston rod with an M27x2 knuckle thread and PT1/2 ports. The adjustable pneumatic cushion, with a 28 mm cushion length, decelerates the piston smoothly at both ends of the stroke. With a body length A of 203 mm, its total extended length reaches 1603 mm, making it ideal for long-reach material handling and pressing tasks where sensor feedback is essential.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400S Is Used
Automated Pallet Transfer
The 1400 mm stroke and 6136 N push force at 0.5 MPa reliably transfer heavy pallets across roller conveyors, with the built-in magnet providing end-of-stroke confirmation via CMSG sensors.
Heavy-Duty Clamping & Fixturing
Delivers up to 11045 N of clamping force at 0.9 MPa for securing large weldments or composite layups in jigs, with sensor feedback ensuring the clamp is fully engaged before the cycle starts.
Long-Reach Pusher Systems
Ideal for pushing large cartons or bins off a main line onto a spur. The 32 mm rod and tie-rod construction provide the rigidity needed for a 1400 mm stroke in a distribution center.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400S the Right Cylinder?
Select the SC125X1400S for high-force, long-stroke applications requiring position sensing. If your force requirement is lower, consider stepping down to the 100 mm bore SC100 series, which provides 3927 N of push force at 0.5 MPa. For even greater force, the 160 mm bore SC160 series delivers 10053 N at the same pressure.
For this 1400 mm stroke, managing side loads is critical to prevent rod bearing wear and bending. Always guide the load externally with a linear rail or rod guide, or consider a guided cylinder. For a direct replacement, match these five points exactly: 125 mm bore, 1400 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting style.
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 SC125X1400S 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. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. As a standard double-acting cylinder, the SC125X1400S will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift. To safely hold a load without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
