About the Airtac SC80 Standard Cylinder SC80X650S
The SC80X650S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 650 mm stroke. At 0.5 MPa air pressure it generates 2513 N of push force and 2268 N on the pull stroke, while at the maximum operating pressure of 0.9 MPa the extending thrust reaches 4523 N. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide robust deceleration for mid-to-heavy payloads.
This model includes the factory-installed -S magnet, a ring magnet embedded in the piston that allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The body length A is 182 mm, giving a total extended length of approximately 832 mm. Standard PT1/8 ports and an M20x1.5 rod thread keep the cylinder compatible with common pneumatic fittings and rod-end accessories.

Where the Airtac SC80 Standard Cylinder SC80X650S Is Used
Conveyor Diverter Gates
The 650 mm stroke and 2513 N push force at 0.5 MPa reliably actuate diverter gates and lane sorters on medium-duty package-handling conveyors. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors.
Woodworking Clamp Carriages
Delivers a long, controlled 650 mm travel for panel-saw clamp carriages or edge-banding feed mechanisms. The adjustable air cushion protects tooling at both ends of the stroke.
Grain Silo Slide Gates
Operates heavy slide gates on silos and hoppers with 4523 N of available force at 0.9 MPa. The magnetic piston lets operators add sensors to confirm full-open or full-closed gate status remotely.
Is the Airtac SC80 Standard Cylinder SC80X650S the Right Cylinder?
Choose the SC80 bore when your application needs between roughly 2500 N and 4500 N of push force from a standard 0.15–1.0 MPa air supply. If the load is lighter and you can accept around 1559 N at 0.5 MPa, stepping down to the SC63 reduces envelope size and air consumption. For heavier loads above 3900 N at 0.5 MPa, the SC100 bore delivers 3927 N at the same pressure.
At a 650 mm stroke, the unsupported portion of the 25 mm rod can experience bending under side loads. Fit an external linear guide or rod-alignment coupler to protect the rod bearing and piston seals from premature wear. When replacing an existing cylinder, match five points: 80 mm bore, 650 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style (no accessory bracket).
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 SC80X650S FAQ
At 0.5 MPa (approx. 73 psi) the cylinder pushes with 2513 N and pulls with 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. These values assume a clean, filtered air supply and a static piston; dynamic force is slightly lower due to friction and flow losses.
Yes. The -S suffix in the model code means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional brackets or modifications.
