About the Airtac SC80 Standard Cylinder SC80X305TC
The AirTAC SC80X305TC is an 80 mm bore double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). With a 305 mm stroke and a 25 mm diameter piston rod, this model suits medium-duty linear actuation tasks where a pivoting mount is required.
This cylinder is factory-configured with the TC centre trunnion mount, which includes the TCM1 bracket (part code F-SC80TC). The trunnion allows the cylinder body to pivot as it strokes, absorbing angular misalignment in swinging or articulating machine sections. Its adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact noise and wear.

Where the Airtac SC80 Standard Cylinder SC80X305TC Is Used
Conveyor Diverter Gates
The centre trunnion mount lets the cylinder pivot as it pushes a diverter gate across a conveyor, sorting packages or materials without binding the rod.
Welding Fixture Clamps
Provides 2513 N of clamping force at standard shop air to hold steel fabrications in a welding jig, with the trunnion absorbing fixture misalignment.
Agricultural Implement Control
Operates pivoting chutes or deflector plates on harvesters and spreaders, where the 305 mm stroke gives enough travel for full range of motion.
Is the Airtac SC80 Standard Cylinder SC80X305TC the Right Cylinder?
Choose the SC80 bore when your application needs between roughly 2500 N and 4500 N of push force. If your load is lighter, stepping down to the SC63 (1559 N at 0.5 MPa) can reduce air consumption and physical size. For heavier loads, the SC100 provides 3927 N at the same 0.5 MPa pressure. At a 305 mm stroke, the 25 mm rod is well-supported inside the barrel, but any external side load must be managed with an external guide rail or rod-alignment coupler to prevent bending stress on the rod bearing. To replace an existing SC80X305TC, match the 80 mm bore, 305 mm stroke, PT port thread, TC centre trunnion mount, and ensure the magnet option (-S) matches your sensor setup.
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 SC80X305TC FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80X305TC is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift. For load holding, add a pilot-operated check valve or an external mechanical rod lock.
