About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80STC
The SC160X80STC is a robust double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa. Its 160 mm bore and 40 mm diameter piston rod are built into a tie-rod construction, providing a compact 239 mm body length for an 80 mm stroke.
This model is factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion (TC) mount, supplied with the TCM1 bracket, allowing the cylinder to pivot during operation. With PT ports and TPU seals, it operates reliably in standard temperatures from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80STC Is Used
Heavy Die Press Actuation
Provides the high force needed to close and hold medium-to-large forming dies in metal stamping or plastic thermoforming lines, where the trunnion mount allows the cylinder body to align with the press motion.
Pallet Stop and Lift Stations
The 18095 N max force at 0.9 MPa can reliably raise heavy pallets or stop loaded conveyors, with the magnetic piston enabling end-of-stroke sensing for automated material handling systems.
Pivoting Clamp Fixtures
The integrated TC centre trunnion mount is ideal for welding or assembly jigs where the cylinder must swing, delivering a powerful, controlled clamping force on large structural components.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80STC the Right Cylinder?
Select the SC160 when your application requires a high-force actuator in the 10 kN class at standard plant pressure. If your force needs are lower, stepping down to an SC125 bore reduces push force to 6136 N at 0.5 MPa, saving space and air consumption. For even higher demands, the SC200 bore provides 15708 N at the same pressure.
For a direct replacement, match five key points: the 160 mm bore, 80 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC160TC bracket, and the built-in magnet for sensor compatibility. This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profiles.
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 SC160X80STC FAQ
At 0.5 MPa, the theoretical push force is 10053 N. At a common industrial pressure of 0.7 MPa, it increases to 14074 N, and reaches a maximum of 18095 N at the 0.9 MPa operating limit. The theoretical maximum is 2050 kgf at 1.0 MPa.
Direct interchangeability is not guaranteed. The SC series is a tie-rod cylinder, not an ISO 15552 profile. For a successful replacement, you must match the 160 mm bore, 80 mm stroke, PT port size, centre trunnion (TC) mounting style, and the magnetic piston feature exactly with another AirTAC SC cylinder.
