About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300TC
The AirTAC SC160X300TC is a double-acting pneumatic cylinder delivering substantial force for heavy-duty industrial automation. At 0.5 MPa air pressure, it generates 10053 N pushing force and 9425 N pulling force, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa. This model features a 300 mm stroke, 40 mm diameter piston rod with M36x2 thread, and a 29 mm adjustable air cushion to decelerate high-inertia loads smoothly.
This specific configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC160TC), allowing the cylinder to pivot and accommodate angular motion during operation. The body length A is 239 mm, resulting in a total extended length of 539 mm. With PT3/4 port threads and standard TPU seals, it operates reliably in temperatures from -20 to +70 °C. As part of the ISO 6430 class for large bores, its speed range is 30-500 mm/s.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300TC Is Used
Heavy Press & Clamping
Delivers up to 18095 N of force at 0.9 MPa for powerful clamping, pressing, and riveting operations in automotive and metal fabrication cells.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder to swing, making it ideal for actuating diverter gates and sorting mechanisms on heavy-duty material handling conveyors.
Large Valve Actuation
Provides the high thrust needed to operate large industrial ball or butterfly valves, with the trunnion mount absorbing the arc motion of the actuator linkage.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300TC the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 125 mm bore SC125 series, which provides 6136 N push force at 0.5 MPa. If even greater power is required, the 200 mm bore SC200 series offers 15708 N at the same pressure. This 300 mm stroke model uses a 40 mm diameter rod; for long-stroke applications with potential side loads, an external guide or guided cylinder is strongly recommended to prevent rod bending and ensure bearing life. When replacing an existing cylinder, match five key points: 160 mm bore, 300 mm stroke, PT3/4 port thread, centre trunnion (TC) mounting with TCM1 bracket, and confirm the magnet requirement (this model has no built-in magnet).

- ✓ 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 SC160X300TC FAQ
At 0.7 MPa (7 bar), the theoretical pushing force is 14074 N. The maximum operating force at 0.9 MPa is 18095 N. Always apply a safety factor to these theoretical values for dynamic loads.
No. The SC160X300TC is a standard double-acting cylinder and will not hold position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end. For load holding, you must add an external rod lock or a pilot-operated check valve.
