About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X280TC
The SC125X280TC is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 280 mm stroke and a robust 32 mm diameter piston rod, this ISO 6430 class tie-rod cylinder is built for heavy linear actuation tasks.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (part code F-SC125TC), which allows the cylinder to pivot during operation, ideal for swinging or articulating loads. The standard PT port thread is 1/2 inch, and the adjustable air cushion (28 mm) decelerates the piston smoothly at the end of the stroke.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X280TC Is Used
Heavy Part Transfer
Shuttles large fabricated metal components or heavy pallets between conveyor lines, using the 6136 N push force at 0.5 MPa to move substantial masses reliably.
Industrial Press Feed
Feeds thick sheet metal or heavy blanks into a stamping press, leveraging the 11045 N maximum force at 0.9 MPa for demanding high-cycle insertion tasks.
Pivoting Clamp Actuator
Operates a large pivoting weld fixture clamp, where the centre trunnion mount allows the cylinder body to swing freely, accommodating the arc of the clamping arm.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X280TC the Right Cylinder?
Select the SC125 bore when your application requires between 6136 N (push at 0.5 MPa) and 11045 N (push at 0.9 MPa) of force. If your force requirement is slightly lower, stepping down to the SC100 bore provides 3927 N at 0.5 MPa. For higher forces, the SC160 bore offers 10053 N at the same pressure. For this 280 mm stroke, ensure the load is guided externally if side forces are present, as the 32 mm rod can experience bending moments under unsupported side loads.
To guarantee a correct replacement, match five key specifications: the 125 mm bore, 280 mm stroke, 1/2 inch PT port thread, centre trunnion (TC) mounting with the F-SC125TC bracket, and the absence of a built-in magnet. This ensures dimensional and functional interchangeability with an existing AirTAC SC series 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 SC125X280TC FAQ
At the standard operating pressure of 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
The TC mount is a centre trunnion pivot that allows the cylinder to swing during operation, ideal for applications where the load moves through an arc. This model ships with the TCM1 trunnion mounting bracket (order code F-SC125TC) for direct installation onto a pivoting fixture.
