About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X180S
The SC160X180S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 160 mm bore with a 180 mm stroke. At 0.5 MPa it generates a push force of 10053 N, placing it in the heavy-duty industrial class for pressing, clamping, and lifting operations. This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to be mounted directly on the barrel for rod-position feedback.
Engineered with a 40 mm diameter piston rod and M36x2 knuckle thread, the cylinder handles substantial side loads when properly guided. The adjustable air cushion (29 mm length) decelerates the piston smoothly at each end of stroke, protecting end caps at speeds up to 500 mm/s. Ports are PT3/4, and the body length A is 239 mm, giving a total extended length of approximately 419 mm. Operating pressure spans 0.15–1.0 MPa with standard TPU seals rated for -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X180S Is Used
Heavy Press & Clamp Fixtures
The 10053 N push force at 0.5 MPa makes this cylinder ideal for hydraulic-press alternatives in assembly jigs, riveting stations, and high-force clamping where clean compressed air is preferred.
Palletising & Material Handling
With 180 mm stroke and sensor-ready magnet, the SC160X180S accurately positions heavy pallets or lifts large components in end-of-line packaging and logistics automation.
Die Cushion & Forming
The adjustable cushion and robust tie-rod construction suit metal-forming and die-cushion applications, where controlled deceleration of heavy tooling is critical for part quality.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X180S the Right Cylinder?
Select the SC160 bore when your application needs a push force above 10000 N at 0.5 MPa. If your load requires less force, the SC125 bore delivers 6136 N push at the same pressure, potentially reducing air consumption and physical size. For higher force demands, the SC200 bore provides 15708 N push at 0.5 MPa.
For this 180 mm stroke, side-load bending moment on the 40 mm rod is moderate, but any off-axis load still requires an external guide or linear rail to protect the rod bearing and seal. When replacing an existing cylinder, match five points exactly: 160 mm bore, 180 mm stroke, PT3/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration.
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 SC160X180S 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, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in SC160X180S indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the barrel for non-contact end-of-stroke or mid-stroke position sensing.
