About the Airtac SC80 Standard Cylinder SC80X76STC
The SC80X76STC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 76 mm stroke. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of0.9 MPa, driven by a 25 mm diameter piston rod.
This model is factory-configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion pivot mount (-TC suffix). The TC mount, supplied with the TCM1 trunnion bracket (part code F-SC80TC), allows the cylinder body to pivot, making it ideal for swinging loads. The body length A is 182 mm, giving a total extended length of approximately 258 mm.

Where the Airtac SC80 Standard Cylinder SC80X76STC Is Used
Pivoting Diverter Gate
The centre trunnion mount allows the cylinder body to pivot as it actuates a diverter gate on a conveyor line, handling 2513 N of force to reliably sort packages.
Clamping Fixture Swing Arm
Ideal for swinging a heavy-duty clamp into place on a welding fixture. The built-in magnet provides end-of-stroke confirmation via CMSG sensors for automated cycle start.
Tilt Mechanism Actuator
Powers a bin or hopper tilt mechanism. The 25 mm rod and adjustable air cushion at both ends ensure smooth, controlled motion under a shifting centre of gravity.
Is the Airtac SC80 Standard Cylinder SC80X76STC the Right Cylinder?
Choose the SC80X76STC when your application requires a mid-range force of around 2513 N at standard shop air and a pivoting cylinder body. If you need more force, stepping up to the 100 mm bore provides 3927 N at0.5 MPa; for a lighter, more compact solution, the 63 mm bore delivers 1559 N. The centre trunnion mount allows the cylinder to swing in a single plane, absorbing misalignment from a pivoting load.
For a direct replacement, match these five points: 80 mm bore, 76 mm stroke, PT port thread, centre trunnion (TC) mount with its TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with one.
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 SC80 Standard Cylinder SC80X76STC FAQ
At the standard operating pressure of0.5 MPa, this 80 mm bore cylinder produces a push force of 2513 N and a pull force of 2268 N. At the maximum operating pressure of0.9 MPa, the push force increases to 4523 N.
The -TC suffix means the cylinder is built with a centre trunnion pivot and includes the TCM1 mounting bracket (part code F-SC80TC). This allows the entire cylinder body to pivot around its centre point, which is essential for applications where the load moves through an arc. The mount is fixed at the cylinder's midpoint.
