About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150FA
The SC125X150FA 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 150 mm stroke and a rigid 32 mm diameter piston rod, this ISO 6430 class tie-rod actuator is built for heavy linear work.
This model is configured with an FA front rectangular flange (F-SC125FA) for secure panel or bulkhead mounting. The adjustable air cushion at each end decelerates the piston smoothly over a 28 mm cushion length, protecting the end caps during high-cycle operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150FA Is Used
Heavy Press & Clamping
Generates over 1.1 metric tons of force at 0.9 MPa, ideal for hydraulic-replacement clamping fixtures and forming presses where clean compressed air is preferred.
Bulkhead Automation
The FA front flange allows the cylinder body to be rigidly mounted through a machine panel, keeping the 150 mm stroke action fully supported on the process side.
Pallet & Container Handling
Delivers the high push force needed for pallet dispensers, container lift gates, and heavy-duty material stops in logistics centres.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150FA the Right Cylinder?
For applications needing more force, stepping up to the SC160 bore provides 10053 N of push at 0.5 MPa. If a shorter, lighter cylinder is sufficient, the SC100 bore offers 3927 N at the same pressure. Always match replacement cylinders on five points: bore, stroke, port thread (PT), mounting accessory (FA front flange), and magnet option (none on this model).
At a 150 mm stroke, the rod bearing is well-supported for axial loads. If side loads are present in the application, consider an external guide rail system to protect the rod and bearing from bending moments.
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 SC125X150FA 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 at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with matching stroke, PT ports, and FA front flange mount.
