About the Airtac SC80 Standard Cylinder SC80X80TC
The SC80X80TC is an 80 mm bore, 80 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates 2513 N of push force and 2268 N of pull force when supplied with 0.5 MPa air, making it a robust mid-range actuator for industrial tasks. The cylinder body length is 182 mm, and it uses a 25 mm diameter piston rod with an M20x1.5 male thread for tooling attachment.
This model is factory-configured with a TC centre trunnion mount, supplied together with the TCM1 bracket (order code F-SC80TC). The trunnion allows the cylinder to pivot during operation, which is essential for applications where the load moves through an arc. The adjustable air cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact and noise.

Where the Airtac SC80 Standard Cylinder SC80X80TC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to swing, making it ideal for actuating diverter gates on conveyor systems. The 80 mm stroke provides a crisp, defined movement to redirect packages or materials between lanes.
Clamping & Welding Fixtures
Delivers a powerful 4523 N clamping force at 0.9 MPa. The pivoting action of the TC mount enables the cylinder to swing a clamp arm into position and apply direct holding pressure for machining or welding operations.
Agricultural Machinery Linkages
Used to actuate pivoting linkages on planting or harvesting equipment. The 25 mm rod and robust tie-rod construction handle dirty, demanding environments, while the trunnion mount absorbs the linkage's angular motion.
Is the Airtac SC80 Standard Cylinder SC80X80TC the Right Cylinder?
Choose the SC80 when your application needs between roughly 2500 N and 4500 N of force at standard plant air pressures. If your load requires less force, stepping down to the SC63 bore (1559 N push at 0.5 MPa) can reduce air consumption and physical size. For higher force demands, the SC100 bore provides 3927 N at the same 0.5 MPa pressure.
To ensure a successful replacement, match five key points: the 80 mm bore, the 80 mm stroke, the PT1/8 port thread, the TC centre trunnion mounting style, and the absence of a magnet on this specific model. The trunnion pivot point must be correctly aligned and supported to prevent bending moments on the rod. For strokes over 300 mm in this bore size, always assess side loads and consider an external guide rail to protect the rod bearing from premature wear.
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 SC80X80TC FAQ
At the standard operating pressure of 0.7 MPa, this cylinder provides 3518 N of push force and approximately 3175 N of pull force. The maximum push force at the 0.9 MPa operating limit is 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Only if your machine is designed to accept a pivoting cylinder. The TC centre trunnion mount (F-SC80TC) allows the cylinder body to rotate, unlike a fixed foot mount. You must ensure the mounting structure supports the trunnion pins and that the rod end can follow the resulting arc of motion without binding.
