About the Airtac SC80 Standard Cylinder SC80X750SN
The SC80X750SN is an 80 mm bore, 750 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. At 0.5 MPa it provides 2513 N push and 2268 N pull, stepping up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust mid-range actuator for industrial linear motion.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and is fitted with NBR (nitrile) seals (-N suffix) for standard temperature operation from -20 to +70 °C. The 25 mm diameter piston rod and 28 mm adjustable air cushion ensure smooth deceleration across the 750 mm stroke, with a compact body length A of just 182 mm.

Where the Airtac SC80 Standard Cylinder SC80X750SN Is Used
Material Transfer
Pushes or diverts boxes and totes on a packaging line, with the 750 mm stroke bridging wide conveyor gaps and sensor confirmation of each cycle.
Press-Fit Assembly
Delivers up to 4523 N of force at 0.9 MPa for installing bearings or bushings, with the adjustable cushion protecting the tooling at the end of the stroke.
Bin Tipping Station
Powers a 750 mm stroke tipping mechanism for bulk bins, using the built-in magnet to signal full extend and retract positions for automated control.
Is the Airtac SC80 Standard Cylinder SC80X750SN the Right Cylinder?
Select the SC80 bore when your application requires a push force between the SC63 (1559 N at 0.5 MPa) and the SC100 (3927 N at 0.5 MPa). For this 750 mm stroke, carefully evaluate side-load conditions; an unsupported 25 mm rod at full extension is susceptible to bending. Use an external linear guide or a guided cylinder if lateral forces are present.
To replace an existing cylinder, match all five critical points: 80 mm bore, 750 mm stroke, PT1/8 port thread, the built-in magnet for sensor compatibility, and the basic (no accessory) mounting configuration. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X750SN FAQ
At 0.7 MPa supply pressure, the theoretical push force on the 80 mm bore piston is 3518 N. The pull force on the return stroke, accounting for the 25 mm rod area, is 3167 N.
No. The SC80X750SN is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end. For load holding, an external rod lock or pilot-operated check valve is required.
