About the Airtac SC80 Standard Cylinder SC80X650
The AirTAC SC80X650 is an 80 mm bore, 650 mm stroke double-acting pneumatic cylinder from the SC tie-rod series. At 0.5 MPa air pressure it produces 2513 N of push force and 2268 N on the pull stroke, making it a capable mid-range actuator for general industrial automation. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration, while the total extended body length reaches approximately 832 mm (body length A of 182 mm plus the 650 mm stroke).
This model is configured with the standard TPU seals for a working temperature range of -20 to +70 °C and PT3/8 threaded ports. It is a basic mounting variant, supplied without brackets, giving you the flexibility to choose from the full range of AirTAC SC accessories like foot mounts, flanges, or trunnions. The cylinder is rated for an operating pressure of 0.15 to 1.0 MPa and a maximum push force of 4523 N at 0.9 MPa.

Where the Airtac SC80 Standard Cylinder SC80X650 Is Used
Material Transfer Gates
The 650 mm stroke and 2513 N push force at 0.5 MPa are well-suited for actuating diverter gates on wide conveyor lines, reliably pushing products onto a secondary lane.
Press-Feed Mechanisms
Delivers a consistent 650 mm linear feed stroke for moving sheet metal or composite blanks into a stamping press, with the adjustable cushion protecting tooling from impact shock.
Pallet Layer Positioning
Used to push or align palletized layers on an accumulation table, where the long stroke and high force capacity ensure positive positioning of heavy loads.
Is the Airtac SC80 Standard Cylinder SC80X650 the Right Cylinder?
For applications requiring slightly less force, stepping down to a 63 mm bore (SC63 series) provides 1559 N of push at 0.5 MPa in a more compact body. If your load demands a higher safety factor, the 100 mm bore SC100 series offers 3927 N at the same pressure. At a 650 mm stroke, the 25 mm rod is robust, but any significant side loading requires an external guide rail or rod-alignment coupler to prevent bending stress on the rod bearing and premature seal wear.
To ensure a correct replacement, match these five points: the 80 mm bore, the 650 mm stroke, the PT3/8 port thread, the basic mounting configuration, and the absence of a built-in magnet. This cylinder is a direct dimensional replacement for another AirTAC SC80 tie-rod unit with the same specifications.
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 SC80X650 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force on the retract stroke is 3175 N. The maximum push force at 0.9 MPa is 4523 N.
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 for position feedback, you would need to order the SC80X650-S variant, which includes the magnet.
