About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X700FA
The AirTAC SC125X700FA is a double-acting tie-rod cylinder with a 125 mm bore and a 700 mm stroke, delivering a substantial 6136 N of push force at 0.5 MPa (11045 N at the maximum operating pressure of 0.9 MPa). This model is equipped with a front rectangular flange (FA) for secure panel mounting, making it ideal for applications where the cylinder body must be rigidly fixed to a machine frame.
Built with a 32 mm diameter piston rod and an M27x2 rod thread, the SC125X700FA provides excellent column strength for this stroke length. The cylinder features an adjustable air cushion (28 mm length) to decelerate the piston smoothly at the end of travel, reducing impact and noise. As an ISO 6430 class cylinder, it operates within a speed range of 30-500 mm/s and uses a PT1/2 port for air connections.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X700FA Is Used
Heavy Press & Clamping
The 11045 N maximum push force at 0.9 MPa makes this cylinder ideal for heavy-duty clamping fixtures, forming presses, and stamping operations requiring high force in a compact tie-rod package.
Material Handling Gates
With a 700 mm stroke and front flange mounting, the SC125X700FA can actuate large diverter gates or stops on conveyor lines handling pallets or heavy bulk materials.
Structural Testing Rigs
The high force output and tie-rod construction suit static or cyclic load testing frames, where the cylinder applies controlled force to structural components or material samples.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X700FA the Right Cylinder?
For applications requiring slightly less force, the SC100 bore delivers 3927 N at 0.5 MPa, while the SC160 bore steps up to 10053 N for heavier loads. At a 700 mm stroke, ensure the load is guided and side forces are minimized to prevent bending stress on the 32 mm rod; an external guide or a guided cylinder is recommended for unsupported side loads. To replace an existing unit, match the 125 mm bore, 700 mm stroke, PT1/2 port thread, front flange FA mounting (accessory F-SC125FA), and confirm the magnet requirement—this model has no built-in magnet.
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 SC125X700FA 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.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It can only directly replace another AirTAC SC tie-rod cylinder or an equivalent tie-rod design with matching bore, stroke, port, and mounting dimensions.
