About the Airtac SC80 Standard Cylinder SC80X405
The AirTAC SC80X405 is an 80 mm bore double-acting tie-rod cylinder with a 405 mm stroke, delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. Its 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide reliable deceleration for mid-stroke industrial tasks.
With a body length A of 182 mm, the extended length reaches approximately 587 mm. The cylinder uses PT1/8 ports and an M20x1.5 rod thread, and is rated for -20 to +70 °C with standard TPU seals. This genuine AirTAC SC unit is a compact tie-rod design, shorter than an equivalent ISO 15552 cylinder.

Where the Airtac SC80 Standard Cylinder SC80X405 Is Used
Conveyor Diverter
Actuates a 405 mm stroke diverter gate on a packaging line, using the 2513 N push force at 0.5 MPa to redirect cartons between lanes.
Clamping Fixture
Provides 4523 N of clamping force at 0.9 MPa for holding large weldments or castings during machining, with the 28 mm cushion absorbing end-of-stroke shock.
Pallet Lift Assist
Powers a 405 mm vertical lift assist on a pallet dispenser, retracting under load with 2268 N pull force at 0.5 MPa to lower an empty pallet stack.
Is the Airtac SC80 Standard Cylinder SC80X405 the Right Cylinder?
For higher force, step up to the 100 mm bore SC100 series which provides 3927 N at 0.5 MPa. If 80 mm bore force is sufficient but a shorter stroke is needed, the SC80 series offers standard strokes from 25 mm upward. At 405 mm stroke, ensure the rod is not subjected to significant side load; an external guide or guided cylinder is recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five points: 80 mm bore, 405 mm stroke, PT port thread, basic (no bracket) mounting, and confirm whether a magnet (-S suffix) is required for sensor mounting. This model has no built-in magnet.
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 SC80X405 FAQ
At 0.5 MPa the push force is 2513 N and 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 SC80X405 is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. For load holding without live pressure, add a pilot-operated check valve or an external mechanical rod lock.
