About the Airtac SC80 Standard Cylinder SC80X75CB
The SC80X75CB is an 80 mm bore, 75 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust actuator for medium-duty industrial tasks. The 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth end-of-stroke deceleration.
This model is configured with a rear double clevis (CB) mounting, part code F-SC80CB, which allows the cylinder to pivot during operation, ideal for applications with angular movement. The standard PT1/8 port and TPU seals suit filtered compressed air systems operating from -20 to +70 °C. The total body length is 182 mm plus the 75 mm stroke.

Where the Airtac SC80 Standard Cylinder SC80X75CB Is Used
Agricultural Equipment
Operates chute diverters and hopper gates on harvesters and conveyors. The rear clevis mount handles the swinging motion of discharge chutes.
Conveyor Diverters
Pivots a diverter arm to sort packages or bulk materials on a conveyor line. The 2513 N force at 0.5 MPa reliably pushes heavy items off the belt.
Dump Body Latches
Secures or releases the tailgate on small dump trailers. The clevis mount allows the cylinder to swing as the bed tilts, preventing rod bending.
Is the Airtac SC80 Standard Cylinder SC80X75CB the Right Cylinder?
For higher force, step up to the 100 mm bore SC100 series, which provides 3927 N at 0.5 MPa. For a lighter, more compact solution, the 63 mm bore delivers 1559 N. When replacing, match five key points: 80 mm bore, 75 mm stroke, PT port thread, CB rear double clevis mount, and the non-magnetic piston.
This cylinder uses a tie-rod construction and is shorter than an ISO 15552 profile, so it is not a drop-in replacement for ISO 15552 cylinders. Verify the pivot pin dimensions for the F-SC80CB clevis bracket against your existing setup.
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 SC80X75CB FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80X75CB is a double-acting cylinder and will not hold position if pressure is lost or the valve is centered. For load holding, you must add a pilot-operated check valve or an external mechanical rod lock.
