About the Airtac SC80 Standard Cylinder SC80X350CB
The SC80X350CB is a double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. Its 350 mm stroke is paired with a 25 mm diameter piston rod and a 28 mm adjustable air cushion at each end, providing reliable deceleration for mid-range industrial strokes.
This model is configured with a CB rear double clevis mount (fork), supplied as accessory F-SC80CB, allowing the cylinder to pivot during operation. It features standard PT1/8 ports and operates with TPU seals across a temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X350CB Is Used
Agricultural Equipment Actuation
The rear clevis mount and robust 2513 N force at 0.5 MPa make this cylinder ideal for pivoting linkages on harvesters, planters, and tillage equipment, where it can reliably operate gates and chutes in dusty conditions.
Conveyor Diverter Gates
With a 350 mm stroke and 4523 N of max force, the SC80X350CB effectively pushes heavy diverter gates on material handling conveyors, sorting bulk aggregates or packaged goods between different lanes.
Welding Fixture Clamping
The pivoting double clevis allows the cylinder to swing into position for clamping large weldments. Its 28 mm cushion absorbs impact, preventing fixture vibration and ensuring consistent part alignment.
Is the Airtac SC80 Standard Cylinder SC80X350CB the Right Cylinder?
For applications requiring higher force, stepping up to the 100 mm bore SC100 series provides 3927 N of push at 0.5 MPa. For a lighter, more compact solution, the 63 mm bore offers 1559 N. This 350 mm stroke length is within the standard range for the 80 mm bore, but always ensure the rod is not subjected to direct side loading; external guides or a guided cylinder are recommended to protect the rod bearing from bending moments.
To ensure a drop-in replacement, match five key specifications: an 80 mm bore, a 350 mm stroke, PT port threads, the CB rear double clevis mounting, and the absence of a built-in magnet on this non-S variant.
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 SC80X350CB FAQ
At the standard operating pressure of 0.5 MPa, the cylinder produces 2513 N of push force and 2268 N of pull force on the retract stroke. The maximum push force at 0.9 MPa is 4523 N.
This specific model includes a factory-configured CB rear double clevis (fork) mount. For a direct replacement, the existing cylinder must have the same 80 mm bore, 350 mm stroke, PT ports, and a rear clevis pivot. The mounting is integral to the part number; it cannot be removed or retrofitted to a basic cylinder.
