About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75STC
The SC160X75STC is a double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). With a 75 mm stroke and a 40 mm diameter piston rod, it is built for short, powerful linear movements in heavy industrial machinery.
This model features a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, and a TC centre trunnion mount (supplied with the TCM1 bracket, part code F-SC160TC) for pivoting applications. The 29 mm adjustable air cushion decelerates the high-inertia load smoothly at stroke end, protecting the cylinder and your tooling.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75STC Is Used
Heavy Part Clamping
Generates up to 18095 N of force at 0.9 MPa to securely clamp large weldments or castings in heavy fabrication fixtures, using the trunnion mount to pivot into position.
Die Cushion Actuation
Provides a powerful, controlled stroke for die cushion pins in large stamping presses, where the adjustable cushion decelerates the high-force return stroke.
Pivoting Conveyor Gate
The TC centre trunnion mount allows the cylinder to swing, making it ideal for actuating a heavy diverter gate on a mining or aggregate conveyor line.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75STC the Right Cylinder?
Select the SC160 when your application requires a force class around 10053 N at standard plant pressure. If you need a more compact solution with slightly lower force, the SC125 bore provides 6136 N push at 0.5 MPa. For higher force requirements, the SC200 bore steps up to 15708 N.
This 75 mm stroke is well within the 1500 mm maximum standard stroke for bore 160. To ensure a direct replacement, match five points: 160 mm bore, 75 mm stroke, PT port thread, TC centre trunnion mounting, and the built-in magnet for sensor compatibility. The SC is a tie-rod cylinder and 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 SC160X75STC FAQ
At 0.7 MPa operating pressure, the theoretical push force is 14074 N. The maximum push force at the 0.9 MPa limit is 18095 N.
No. As a standard double-acting cylinder, it will drift or drop if pressure is lost. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
