About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500SFA
The SC125X500SFA is a double-acting tie-rod cylinder delivering 6136 N push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 500 mm stroke and a 32 mm piston rod, this ISO 6430 class cylinder is built for heavy linear actuation where robust force and mid-range travel are required.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a front rectangular flange (FA, part F-SC125FA) for secure panel or bulkhead mounting. The adjustable air cushion (28 mm length) decelerates the piston smoothly, protecting end caps during high-cycle operation. Operating on filtered air from 0.15 to 1.0 MPa, it uses standard PT ports and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500SFA Is Used
Heavy Press & Clamping
The 11045 N maximum thrust at 0.9 MPa powers heavy-duty clamping fixtures and small forming presses, with the FA flange ensuring rigid alignment to the machine frame.
Material Handling Gates
Ideal for actuating diverter gates or heavy stops on conveyor lines, where the 500 mm stroke provides ample travel and the magnet allows precise end-of-stroke sensing.
Industrial Automation
A core actuator for large-scale automation cells, providing repeatable 6136 N push force for lifting, positioning, or ejecting heavy components in a 24/7 production environment.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500SFA the Right Cylinder?
For applications needing less force, stepping down to the SC100 bore provides 3927 N push at 0.5 MPa, while the SC160 bore offers 10053 N for a significant power increase. At a 500 mm stroke, the 32 mm rod is robust, but significant side loads should be managed with external guides or a guided cylinder to prevent rod bearing wear and bending.
To ensure a correct replacement, match five key points: 125 mm bore, 500 mm stroke, PT port thread, the FA front flange mounting accessory (F-SC125FA), and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125X500SFA 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 AirTAC SC series is a tie-rod cylinder and is shorter than an ISO 15552 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, FA front flange mount, and magnet.
