About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80TC
The SC160X80TC is a double-acting pneumatic cylinder delivering substantial force in a compact 80 mm stroke. At 0.5 MPa, it generates 10053 N pushing and 9425 N pulling, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy clamping and pressing tasks.
This model features a centre trunnion mount (TC), supplied with the TCM1 bracket (F-SC160TC), allowing the cylinder body to pivot during operation. The 40 mm diameter piston rod and 29 mm adjustable air cushion at each end ensure smooth deceleration of high inertial loads, while the PT3/4 port provides ample flow for rapid cycling.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80TC Is Used
Heavy-Duty Clamping
The 10053 N force at 0.5 MPa securely locks workpieces on CNC machining centres and welding fixtures, resisting movement under cutting or joining forces.
Pivoting Press Actuator
The centre trunnion mount allows the cylinder to swing, ideal for toggle presses and articulating mechanical linkages where the actuator must follow an arc.
Bulk Material Gate Control
Operates heavy slide gates on silos and hoppers, providing the high push force needed to shear through packed granular materials with an 80 mm stroke.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X80TC the Right Cylinder?
Select the SC160 when your application requires forces in the 10000-18000 N range at standard plant pressures. For lighter loads, stepping down to the SC125 bore reduces push force to 6136 N at 0.5 MPa, saving energy and space. For higher forces, the SC200 bore provides 15708 N at the same pressure.
When replacing an existing cylinder, match five points exactly: 160 mm bore, 80 mm stroke, PT3/4 port thread, centre trunnion (TC) mounting, and the absence of a magnetic piston. This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders; it must replace another AirTAC SC series or equivalent tie-rod design.
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 SC160X80TC FAQ
At 0.7 MPa operating pressure, the SC160X80TC produces a theoretical pushing force of 14074 N. The maximum force at 0.9 MPa is 18095 N. Always apply a safety factor for real-world dynamic loads.
This specific model (SC160X80TC) includes the centre trunnion mount. The trunnion is integral to the tie-rod assembly. For rigid foot mounting, you would order the basic model and add a foot bracket (F-SC160LB) separately. The trunnion is designed for applications where the cylinder body must pivot.
