About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X750S
The SC125X750S is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 125 mm bore and a 750 mm stroke, this model includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise, non-contact position sensing along the barrel.
This tie-rod cylinder features a robust 32 mm piston rod with M27x2 threads and an adjustable air cushion length of 28 mm to decelerate the piston smoothly at each end of the stroke. The body length A is 203 mm, giving a total extended length of approximately 953 mm. It is an ISO 6430 class cylinder, designed for heavy industrial applications where high force and reliable sensor feedback are required.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X750S Is Used
Heavy Pallet Transfer
Provides the high push force needed to move loaded pallets in automated logistics systems, with magnetic sensors confirming end-of-stroke positions for sequencing.
Press-Fit Assembly
Delivers up to 11045 N of force for pressing bearings or bushings into housings, while the built-in magnet enables precise stroke verification to control insertion depth.
Material Handling Clamp
Acts as a powerful clamping actuator on large fixtures. The adjustable cushion protects the tooling from impact shock, and sensors signal the clamp's open/closed state.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X750S the Right Cylinder?
Select the SC125X750S when your application requires a high-force actuator with integrated position sensing. For a step down in force, the SC100 bore provides 3927 N at 0.5 MPa; for even greater power, the SC160 bore offers 10053 N. This 750 mm stroke is within the standard range for the 125 mm bore, which supports strokes up to 1500 mm.
For strokes of this length, always assess side-loading conditions. An unsupported 32 mm rod extending 750 mm is susceptible to bending under radial forces. To ensure long seal and bearing life, use an external guide rail or a guided cylinder assembly to isolate the rod from any side loads. For replacement, match the bore, stroke, PT port thread, basic mount, and the -S magnet option to ensure full compatibility with your existing sensor setup.
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 SC125X750S 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 increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes. The 'S' suffix in the model code SC125X750S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel for non-contact position detection without any additional brackets.
