About the Airtac SC80 Standard Cylinder SC80X490TC
The SC80X490TC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 490 mm stroke. At 0.5 MPa it generates 2513 N pushing force and 2268 N pulling force, while at the maximum operating pressure of 0.9 MPa the push force reaches 4523 N, driven by a 25 mm diameter piston rod.
This model is factory-configured with a centre trunnion (TC) mount, supplied together with the TCM1 trunnion bracket (order code F-SC80TC). The mounting allows the cylinder to pivot, making it suitable for swinging or articulating loads. Ports are PT1/8 with an adjustable air cushion of 28 mm at each end to decelerate the piston smoothly.

Where the Airtac SC80 Standard Cylinder SC80X490TC Is Used
Conveyor Diverter Gates
The 490 mm stroke and pivoting trunnion mount suit medium-reach diverter arms on packaging or sorting conveyors, where the 2513 N force at 0.5 MPa reliably shifts product lanes.
Clamping & Fixturing
Delivers up to 4523 N of clamping force at 0.9 MPa for holding workpieces in CNC machining centres or welding jigs, with the trunnion allowing the cylinder body to self-align.
Agricultural Equipment Actuation
Operates chute doors or hopper gates on farm machinery. The TPU seals handle -20 to +70 °C ambient temperatures, and the tie-rod construction is serviceable in the field.
Is the Airtac SC80 Standard Cylinder SC80X490TC the Right Cylinder?
Choose the SC80 when the 50 mm bore's 982 N push force at 0.5 MPa is insufficient but the 100 mm bore's 3927 N is more than needed. For this 490 mm stroke, ensure the rod is protected from side loads; long unsupported strokes on a 25 mm rod can experience bending under offset loads. An external guide or a guided cylinder is recommended if side forces are present.
To replace an existing cylinder, match five points: 80 mm bore, 490 mm stroke, PT1/8 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and no built-in magnet. The SC is a tie-rod design, shorter than ISO 15552 cylinders, so dimensional interchangeability is limited to another AirTAC SC or an equivalent tie-rod cylinder.
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 SC80X490TC 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 increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X490TC is a double-acting cylinder and does not lock or hold position when pressure is exhausted. If load holding is required, add a pilot-operated check valve or an external rod brake. The adjustable air cushion only decelerates the piston at stroke end to reduce impact.
