About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X650TC
The SC160X650TC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 160 mm bore with a 650 mm stroke. At 0.5 MPa it generates 10053 N of push force and 9425 N on the pull stroke, making it suitable for heavy linear actuation tasks. The 40 mm diameter piston rod and 29 mm air cushion provide robust guidance and effective end-of-stroke deceleration.
This model is factory-configured with a centre trunnion (TC) mount, supplied together with the TCM1 bracket (order code F-SC160TC). The trunnion allows the cylinder body to pivot, accommodating swinging loads and angular motion. Standard PT ports (PT3/4) and TPU seals with a -20 to +70 °C operating range are fitted, with a total extended body length of approximately 889 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X650TC Is Used
Heavy Press & Clamp Actuation
Delivers over 10 kN at 0.5 MPa for pressing, riveting, or clamping large assemblies in metal fabrication and woodworking.
Swinging Gate or Diverter
The centre trunnion mount allows the cylinder to pivot, ideal for actuating large diverter gates or swing arms on heavy material handling lines.
Construction & Agricultural Machinery
Provides reliable, high-force linear motion for booms, stabilizers, or tool positioning in off-highway equipment operating in dusty conditions.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X650TC the Right Cylinder?
For applications needing slightly less force, stepping down to the 125 mm bore SC125 series provides 6136 N push at 0.5 MPa. This 650 mm stroke is within the standard 1500 mm maximum for the 160 bore. When mounting a cylinder of this length and force class, ensure the structure can react to the full 18095 N thrust available at 0.9 MPa. For strokes over 300 mm with any side load, an external guide or guided cylinder is strongly recommended to protect the 40 mm rod and rod bearing from bending stress.
To replace an existing SC160X650TC, match five points: 160 mm bore, 650 mm stroke, PT3/4 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the absence of a magnet. This ensures dimensional and functional interchangeability with another AirTAC SC tie-rod unit.
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 SC160X650TC FAQ
At the standard 0.5 MPa operating pressure, the cylinder produces 10053 N pushing force and 9425 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N.
No. The SC160X650TC is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston can drift or the load may drop. For load holding, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
