About the Airtac SC80 Standard Cylinder SC80X720
The AirTAC SC80X720 is a double-acting tie-rod cylinder with an 80 mm bore and a 720 mm stroke, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide robust deceleration for mid-to-long stroke linear moves.
With a body length A of 182 mm, the total extended length reaches approximately 902 mm, making it well-suited for material handling gates, press-bed transfers, and packaging machinery where a long, straight push is required. This model uses the standard PT1/4 port thread and TPU seals for operation in ambient temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X720 Is Used
Long-Stroke Material Transfer
Pushes or pulls heavy totes and panels across roller conveyors in packaging and logistics lines, using the full 720 mm reach.
Press-Bed Ejection
Ejects formed parts from stamping or thermoforming press beds where a long, straight stroke clears the tooling zone completely.
Gate and Diverter Actuation
Operates sliding gates or product diverters in chutes and hoppers, leveraging the 2513 N push force to move heavy baffles.
Is the Airtac SC80 Standard Cylinder SC80X720 the Right Cylinder?
Choose the SC80X720 when your application needs the 2513 N push force of the 80 mm bore at 0.5 MPa. If a more compact cylinder is acceptable and force requirements are lower, the 63 mm bore provides 1559 N at the same pressure. For higher force demands, stepping up to the 100 mm bore delivers 3927 N at 0.5 MPa.
For this 720 mm stroke, side loading on the 25 mm rod must be carefully managed. An unsupported long stroke can cause rod bending or premature bearing wear. Use an external linear guide or a guided cylinder assembly to absorb transverse forces. When replacing an existing unit, match five points: 80 mm bore, 720 mm stroke, PT port thread, basic (no accessory) mounting, and the absence of a 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 SC80X720 FAQ
At the standard 0.5 MPa operating pressure, 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 force at 1.0 MPa is 513 kgf.
For strokes of 300 mm and above, side loads can bend the rod or damage the bearing. Mount an external linear guide rail parallel to the cylinder to carry the transverse load, or use a guided cylinder assembly. The SC80X720 itself should only see axial push/pull forces.
