About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160FA
The AirTAC SC125X160FA is a double-acting tie-rod cylinder with a 125 mm bore and 160 mm stroke, factory-assembled with a front rectangular flange (FA) for rigid panel or bulkhead mounting. It generates a substantial 6136 N of push force at 0.5 MPa and can reach 11045 N at the maximum operating pressure of 0.9 MPa, making it a powerful actuator for heavy linear tasks.
This ISO 6430 class cylinder uses a 32 mm diameter piston rod with an M27x2 knuckle thread and PT1/2 ports. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly, protecting the end caps during high-cycle operation. The total body length A is 203 mm, giving an extended length of approximately 363 mm for this 160 mm stroke model.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160FA Is Used
Heavy Press & Clamping
The 11045 N thrust at 0.9 MPa provides ample force for industrial presses, die-casting clamping, and heavy-duty assembly fixtures where rigid front-flange mounting is required.
Material Handling Gates
Operates diverter gates or heavy chute doors on conveyors. The front flange allows direct mounting to the gate frame, with the 32 mm rod resisting bending under high material loads.
Structural Testing Rigs
Delivers controlled, repeatable force for load testing of beams and structural components. The tie-rod construction allows for easy maintenance and seal replacement in demanding test lab environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160FA the Right Cylinder?
Select the SC125 when your application needs force in the 6000–11000 N range. If you require less force, step down to the SC100 bore which provides 3927 N at 0.5 MPa. For higher force demands, the SC160 bore delivers 10053 N at the same pressure. Always match the bore, 160 mm stroke, PT1/2 port thread, and front flange mounting when replacing an existing unit.
At a 160 mm stroke, the rod bearing is well-supported for axial loads, but any significant side load requires an external guide or a guided cylinder to prevent rod bending and premature seal wear. The FA front flange (accessory F-SC125FA) centers the cylinder body on a mounting panel and handles the full thrust reaction at the rod end.
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 SC125X160FA FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, push force increases to 8590 N. The maximum operating push force at 0.9 MPa is 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
The FA suffix indicates this cylinder is equipped with a front rectangular flange. The flange bolts to a flat panel or bulkhead, allowing the cylinder body to be centered through a hole. The specific accessory part code is F-SC125FA. This mounting style handles the full thrust reaction at the rod end.
