About the Airtac SC80 Standard Cylinder SC80X280TC
The SC80X280TC is an 80 mm bore, 280 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod with PT3/8 ports.
This model is factory-configured with a TC centre trunnion mount (supplied with the TCM1 bracket, part F-SC80TC), allowing the cylinder to pivot for swinging or articulating loads. The 28 mm adjustable air cushion decelerates the piston at end-of-stroke to reduce impact, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X280TC Is Used
Conveyor Diverters
The 280 mm stroke and 2513 N push force at 0.5 MPa reliably actuates heavy package diverters and sorting gates on medium-duty conveyor lines.
Clamping & Fixturing
Delivers up to 4523 N at 0.9 MPa for pneumatic clamping stations and welding fixtures, with the centre trunnion mount enabling easy angular alignment.
Agricultural Machinery
Pivoting linkage actuation on tillage or seeding equipment, where the TC trunnion mount absorbs the arc motion and the TPU seals handle dusty, ambient-temperature conditions.
Is the Airtac SC80 Standard Cylinder SC80X280TC the Right Cylinder?
Select the SC80 bore when your application needs between 2513 N and 4523 N of push force. For lighter loads, stepping down to the SC63 bore (1559 N at 0.5 MPa) can reduce air consumption; for heavier demands, the SC100 bore provides 3927 N at 0.5 MPa.
At 280 mm stroke, the 25 mm rod is well-supported within standard limits, but any side load must be managed with an external guide or linear rail—pneumatic tie-rod cylinders are not designed to absorb bending moments. To replace an existing cylinder, match five points: 80 mm bore, 280 mm stroke, PT3/8 port thread, TC centre trunnion mount, and the absence of a magnet (no -S suffix).
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 SC80X280TC 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, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder, so mounting dimensions and body length are not interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with matching stroke, PT ports, and TC trunnion mount.
