About the Airtac SC80 Standard Cylinder SC80X590
The AirTAC SC80X590 is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 590 mm stroke, this model is built for medium-to-heavy linear actuation tasks where a robust tie-rod construction is preferred over a profile cylinder.
This cylinder uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. The total extended body length is approximately 772 mm, factoring in the 182 mm base body length. An adjustable pneumatic cushion decelerates the piston over the final 28 mm of travel, reducing end-of-stroke impact without locking the load.

Where the Airtac SC80 Standard Cylinder SC80X590 Is Used
Material Rejection Gates
Provides the rapid linear stroke needed to divert heavy packages or defective products off a high-speed conveyor line, handling the repetitive impact with a durable tie-rod design.
Press-Fit Assembly Stations
Generates over 4500 N of force at 0.9 MPa for pressing bearings, bushings, or pins into housings, with an adjustable cushion to soften the final insertion impact.
Hopper Door Actuation
Controls the opening and closing of large discharge doors on silos or mixing hoppers, reliably operating in dusty environments with filtered compressed air.
Is the Airtac SC80 Standard Cylinder SC80X590 the Right Cylinder?
For applications requiring slightly less force, stepping down to a 63 mm bore provides 2182 N at 0.7 MPa, while moving up to a 100 mm bore delivers 5497 N at the same pressure. The 590 mm stroke is well within the 1500 mm maximum standard stroke for this bore size.
At this stroke length, ensure the 25 mm rod is adequately supported against side loads. If the load is not guided externally, bending moments can damage the rod bearing and seal. Use an external guide rail or a guided cylinder for non-axial loads. For direct replacement, match the 80 mm bore, 590 mm stroke, PT3/8 ports, basic 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 SC80X590 FAQ
At the standard 0.7 MPa operating pressure, the push force is 3518 N and the pull force is 2268 N. The maximum push force at 0.9 MPa is 4523 N. These values assume a static load; dynamic forces depend on speed and load inertia.
This specific model code does not include the '-S' magnet option, so the piston does not have a built-in magnetic ring. To use CMSG or DMSG sensors, you would need the SC80X590-S variant. Without the magnet, sensors cannot detect the piston position through the barrel.
