About the Airtac SC80 Standard Cylinder SC80X750SCB
The SC80X750SCB is an 80 mm bore double-acting pneumatic cylinder with a 750 mm stroke, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa. This model features a built-in magnet for barrel-mounted sensors and a rear double clevis (CB) mount for pivoting applications, supplied with the F-SC80CB bracket.
With a 25 mm diameter piston rod and PT3/8 ports, the cylinder body measures 182 mm (dimension A), giving a total extended length of approximately 932 mm. The 28 mm adjustable air cushion at each end decelerates the piston smoothly, protecting end caps during high-speed operation within the 30-800 mm/s speed range.

Where the Airtac SC80 Standard Cylinder SC80X750SCB Is Used
Agricultural Equipment
Actuates chutes and diverters on harvesters or sorting lines. The CB rear clevis allows the cylinder to pivot freely, handling the 2513 N push force needed to move heavy crop loads.
Conveyor Diverters
Pivots a diverter arm to sort packages on a high-speed line. The built-in magnet enables end-of-stroke sensing with CMSG/DMSG sensors to confirm each divert cycle.
Welding Fixture Clamping
Clamps large fabricated frames in a pivoting fixture. The double clevis mount provides a stable, swinging anchor point, while the adjustable cushion absorbs impact at the 750 mm stroke end.
Is the Airtac SC80 Standard Cylinder SC80X750SCB the Right Cylinder?
For higher force requirements, stepping up to the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If a shorter, more compact cylinder is sufficient, the 63 mm bore SC63 series offers 1559 N at the same pressure. The 750 mm stroke is within the standard range for this bore.
At this stroke length, the 25 mm rod is vulnerable to bending under side loads. An external guide rail or a guided cylinder is strongly recommended to protect the rod bearings and ensure reliable service life. For a direct replacement, match the 80 mm bore, 750 mm stroke, PT3/8 ports, CB rear double clevis mount, and the built-in magnet for sensor compatibility.
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 SC80X750SCB FAQ
At 0.7 MPa operating pressure, the theoretical push force on the outstroke is 3518 N. The pull force on the retract stroke is 2268 N at 0.5 MPa, reduced by the 25 mm rod area.
Yes, provided the original is an AirTAC SC series or an equivalent tie-rod cylinder. Verify the 80 mm bore, 750 mm stroke, PT3/8 pneumatic ports, rear double clevis (CB) mounting, and the need for a magnetic piston for sensor sensing. This is not an ISO 15552 cylinder, so dimensional interchangeability with ISO profile cylinders is not guaranteed.
