About the Airtac SC80 Standard Cylinder SC80X80CB
The SC80X80CB is an 80 mm bore, 80 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod with M20x1.5 male threads.
This model is configured with a CB rear double clevis mount, providing a pivoting attachment point at the cap end for applications where the cylinder body needs to swing through an arc. The 28 mm adjustable air cushion at both ends decelerates the piston smoothly, reducing end-of-stroke impact. Ports are PT3/8, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X80CB Is Used
Dump Trailer Gate Actuation
The rear clevis mount allows the cylinder to pivot as it raises and lowers a small dump gate or chute on agricultural trailers, handling the 2513 N push force needed to move bulk materials.
Clamp Arm Pivoting
Used in welding fixtures where the cylinder body must pivot. The double clevis provides a stable, aligned swing path for a clamp arm, with the 80 mm stroke providing the clamping travel.
Diverter Gate on Conveyors
Operates a pivoting diverter gate in a material handling line. The CB mount lets the cylinder swing with the gate linkage, directing packages between two conveyor lanes reliably.
Is the Airtac SC80 Standard Cylinder SC80X80CB the Right Cylinder?
For higher force at the same pressure, the SC100 bore steps up to 3927 N push at 0.5 MPa. If space is tighter and less force is acceptable, the SC63 bore provides 1559 N push at 0.5 MPa. The 80 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: 80 mm bore, 80 mm stroke, PT3/8 port thread, the CB rear double clevis mounting (part F-SC80CB), and the absence of a magnet. The SC 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 SC80X80CB FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force on the retract stroke is 2268 N (accounting for the 25 mm rod area). For precise dynamic sizing, factor in your application's friction and load margin.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length (body length A is 182 mm) than a typical ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC80 tie-rod cylinder matching the same mounting, port, and stroke.
