About the Airtac SC80 Standard Cylinder SC80X620
The AirTAC SC80X620 is a double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. With an 80 mm bore and 620 mm stroke, this model uses a 25 mm diameter piston rod with M20x1.5 male threads for secure tooling attachment.
Its total extended body length is approximately 802 mm, based on a 182 mm body length plus the 620 mm stroke. The cylinder features an adjustable pneumatic cushion (28 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. PT3/8 ports and TPU seals with a standard temperature range of -20 to +70 °C complete the build.

Where the Airtac SC80 Standard Cylinder SC80X620 Is Used
Material Transfer
Pushes or diverts medium-weight packages and components on conveyor lines, where the 620 mm stroke bridges a wide gap between belts.
Press-Fit Assembly
Provides up to 4523 N of force at 0.9 MPa for pressing bushings, bearings, or pins into housings with a controlled, cushioned stroke end.
Bin Tipping
Extends to tilt medium-capacity bins or hoppers in agricultural or recycling sorting stations, leveraging the long 620 mm reach.
Is the Airtac SC80 Standard Cylinder SC80X620 the Right Cylinder?
For applications requiring more force, stepping up to the 100 mm bore SC100 series provides 3927 N of push force at 0.5 MPa. If space or force requirements are lower, the 63 mm bore SC63 series offers 1559 N at the same pressure. At a 620 mm stroke, the 25 mm rod is robust, but any significant side loading requires an external guide or a guided cylinder to prevent rod bearing wear and bending. When replacing an existing cylinder, match five key points: 80 mm bore, 620 mm stroke, PT3/8 port thread, basic (no mounting accessory) configuration, and the absence of a 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 SC80X620 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 increases to 4523 N.
No. At a 620 mm stroke, the 25 mm diameter rod is susceptible to bending under side loads. An external linear guide or a rod-supported guided cylinder must be used to absorb lateral forces and protect the rod bearing and seals.
