About the Airtac SC80 Standard Cylinder SC80X275TC
The SC80X275TC is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a solid mid-range actuator for industrial automation. This model combines an 80 mm bore with a 275 mm stroke and includes a centre trunnion mount (TC) for pivoting applications, supplied with the TCM1 bracket.
Built on a proven tie-rod design, the cylinder uses a 25 mm diameter piston rod with M20x1.5 threads and PT3/8 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, protecting the end caps during high-cycle operation. Total body length A is 182 mm, giving an extended length of approximately 457 mm.

Where the Airtac SC80 Standard Cylinder SC80X275TC Is Used
Conveyor Diverter Gates
The 275 mm stroke and trunnion mount let this cylinder swing a diverter gate through an arc, sorting packages or materials on a conveyor line with 2513 N of push force at standard plant air.
Clamping & Fixturing
Delivers up to 4523 N of clamping force at 0.9 MPa for holding workpieces during machining or welding. The centre trunnion allows the clamp arm to pivot clear for part loading.
Hopper & Chute Actuation
Operates discharge gates on hoppers and chutes handling bulk solids. The tie-rod construction handles dusty environments, and the adjustable cushion absorbs the gate's inertia at end-of-travel.
Is the Airtac SC80 Standard Cylinder SC80X275TC the Right Cylinder?
Choose the SC80 when your load requires between 2500 N and 4500 N of thrust at typical plant pressures. If your force need is closer to 1500 N, stepping down to the SC63 (1559 N at 0.5 MPa) can reduce air consumption; if you need over 3900 N at 0.5 MPa, the SC100 (3927 N) is the next step up. The centre trunnion mount (F-SC80TC, includes TCM1 bracket) allows the cylinder to pivot as the load moves through an arc—ideal for clamping or dumping mechanisms.
For this 275 mm stroke, ensure the rod is not subjected to significant side loads; an unsupported 25 mm rod can bend under lateral force. For guided linear motion, pair the cylinder with an external guide rail or consider a guided cylinder. When replacing an existing unit, match bore, stroke, PT3/8 port thread, centre trunnion mounting, and confirm whether a magnet (-S) is required for sensors.
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 SC80X275TC FAQ
At 0.5 MPa (5 bar), the cylinder produces 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf (5027 N).
Yes. The 'TC' suffix means this model is supplied with a centre trunnion mount (part code F-SC80TC, includes TCM1 bracket). It mounts at the cylinder's centre of gravity, allowing the body to pivot as the rod extends and retracts—ideal for loads that move through an arc.
