About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80S
The SC160X80S is a double-acting pneumatic cylinder delivering a substantial push force of 10053 N at 0.5 MPa, rising to 18095 N at the maximum operating pressure of 0.9 MPa. With an 80 mm stroke and a 40 mm diameter piston rod, this model is built for heavy-duty linear applications requiring short, powerful movements. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This genuine AirTAC SC series tie-rod cylinder features a 29 mm adjustable air cushion at each end to decelerate high inertial loads smoothly. The body length A is 239 mm, resulting in a compact extended length for its force class. It operates on filtered air from 0.15 to 1.0 MPa with PT3/4 port threads and an M36x2 rod thread for robust mechanical connections.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80S Is Used
Heavy Part Clamping
Generates over 10,000 N of force at standard line pressure, ideal for securely clamping large weldments or castings during machining or assembly processes.
Industrial Pressing
The short 80 mm stroke and high thrust capacity suit small-bed pressing operations, such as bearing insertion, riveting, or compacting materials in a fixture.
Automated Ejection
With a built-in magnet for sensor confirmation, this cylinder reliably ejects heavy stamped or molded parts from large dies, ensuring a clear tool before the next cycle.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80S the Right Cylinder?
Select the SC160X80S for applications needing high force in a short stroke. If your force requirement is lower, consider stepping down to the SC125 bore, which provides 6136 N of push force at 0.5 MPa. For even greater force, the SC200 bore offers 15708 N at the same pressure. Always ensure the load is guided externally if any side forces are present, as the piston rod bearing is designed for axial loads.
For a direct replacement, match these five attributes: 160 mm bore, 80 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic mounting configuration. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.

- ✓ 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 SC160X80S FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in SC160X80S designates a built-in magnet on the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel's tie-rod slots to detect piston position without additional brackets.
