About the Airtac SC80 Standard Cylinder SC80X400CB
The SC80X400CB is an 80 mm bore, 400 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a substantial 2513 N of push force at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure), making it a robust actuator for medium-to-heavy linear tasks. This model is configured with a rear double clevis (CB) mount, allowing the cylinder body to pivot during operation.
The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide reliable deceleration for the 400 mm stroke. With a body length A of 182 mm, the total extended length is approximately 582 mm. The standard PT3/8 port and M20x1.5 rod thread ensure straightforward pneumatic connections. Operating on filtered air, it has a speed range of 30-800 mm/s and a standard temperature range of -20 to +70 °C with its default TPU seals.

Where the Airtac SC80 Standard Cylinder SC80X400CB Is Used
Agricultural Equipment Actuation
The pivoting action from the CB rear clevis mount and 4523 N of force at 0.9 MPa make this cylinder ideal for controlling heavy chutes, gates, or levers on harvesters and spreaders.
Waste Compactor Ram
Deploy the 400 mm stroke and powerful push force to drive a compactor plate in small-to-medium recycling balers, reliably handling the demanding, repetitive cycle.
Pivoting Diverter Gate
Use the CB clevis mount to create a pivoting diverter arm on a conveyor line. The 80 mm bore provides ample force to redirect packages or bulk materials between lanes.
Is the Airtac SC80 Standard Cylinder SC80X400CB the Right Cylinder?
Selecting the SC80X400CB means choosing an 80 mm bore for its 2513 N force at 0.5 MPa. If your load is lighter, stepping down to a 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For heavier loads, a 100 mm bore provides 3927 N. The 400 mm stroke is within the standard range for this bore, but always ensure the rod is not subjected to high side loads; for long-stroke, side-loaded applications, consider an external guide rail or a guided cylinder.
For a direct replacement, match these five points: 80 mm bore, 400 mm stroke, PT3/8 port thread, the CB rear double clevis mount (part F-SC80CB), and the absence of a built-in magnet. This cylinder is a tie-rod design and is dimensionally interchangeable only with another AirTAC SC80 cylinder of the same configuration, not 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 SC80X400CB FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No, the SC80X400CB is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift or drop under load. The adjustable air cushions only decelerate the piston at the end of stroke. To hold a load safely, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve.
