About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400FA
The AirTAC SC160X400FA is a robust double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa. With a 40 mm diameter piston rod and a 400 mm stroke, it is built for heavy industrial linear motion where substantial force is required.
This model features an FA front rectangular flange (F-SC160FA) for secure panel or end-face mounting. The adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 239 mm, and the total extended length approximates 639 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400FA Is Used
Heavy Press Tool Actuation
Operates clamping and forming tools in hydraulic-style press applications, using the 10053 N force at 0.5 MPa to hold tooling securely during metal forming cycles.
Pallet Transfer Systems
Pushes heavy pallets or skids weighing up to a tonne across roller conveyors, leveraging the 400 mm stroke to index loads between workstations.
Structural Test Rigs
Applies controlled linear force in material testing frames, where the front flange mount provides rigid, accurate alignment for repeatable test results.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400FA the Right Cylinder?
Choose the SC160 bore when your application needs roughly 10000 N of force at standard plant pressure; stepping down to the SC125 bore provides 6136 N at 0.5 MPa, while the larger SC200 delivers 15708 N. For this 400 mm stroke, ensure the load is guided and aligned to prevent side-load bending on the 40 mm rod. A perfect replacement must match the 160 mm bore, 400 mm stroke, PT3/4 port thread, FA front flange mounting, and the absence of a magnet sensor option.
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 SC160X400FA FAQ
At 0.7 MPa operating pressure, the SC160 bore generates a theoretical push force of 14074 N. The pull force on the retract stroke is 9425 N at 0.5 MPa, accounting for the 40 mm rod area.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 types. It directly replaces another AirTAC SC160 tie-rod cylinder with matching stroke, PT port, and FA front flange mount.
