About the Airtac SC80 Standard Cylinder SC80X477
The AirTAC SC80X477 is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). Its 477 mm stroke is well within the 1500 mm maximum standard stroke for the 80 mm bore, making this a standard-configuration actuator for medium-to-long linear movements.
This model features a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. The 28 mm adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 182 mm, giving a total extended length of approximately 659 mm.

Where the Airtac SC80 Standard Cylinder SC80X477 Is Used
Package Diverting
Pushes cartons or totes off a main conveyor line onto a spur. The 477 mm stroke reaches across wide belt sections, and the 2513 N force at 0.5 MPa handles heavy packed loads reliably.
Press-to-Stop Transfer
Moves a workpiece carrier or pallet into a machining station stop. The adjustable cushion protects the fixture from shock, and the 25 mm rod resists bending under guided linear motion.
Pallet Layer Positioning
Shifts a layer of boxes onto a pallet stack. The 80 mm bore provides ample force for dense product layers, and the tie-rod construction withstands dusty warehouse conditions.
Is the Airtac SC80 Standard Cylinder SC80X477 the Right Cylinder?
Choose the SC80 when your application needs between 2513 N and 4523 N of pneumatic force. If you require higher thrust, stepping up to the SC100 bore provides 3927 N at the same 0.5 MPa pressure. For lighter, faster loads, the SC63 bore delivers 1559 N at 0.5 MPa.
For this 477 mm stroke, ensure the load is guided and free of side forces. A long unsupported rod can bend under lateral load, so use an external guide rail or rod-alignment coupler. When replacing an existing cylinder, match five points: 80 mm bore, 477 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and no 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 SC80X477 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, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80X477 is a double-acting cylinder and does not hold its position when air pressure is exhausted or the directional valve is centered. The piston will drift or drop. To hold a load without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
