About the Airtac SC80 Standard Cylinder SC80X300CB
The SC80X300CB is a double-acting pneumatic cylinder delivering a robust 2513 N push force at 0.5 MPa (4523 N at the maximum operating pressure of 0.9 MPa). With an 80 mm bore and 300 mm stroke, this tie-rod actuator uses a 25 mm diameter piston rod with M20x1.5 threads, providing excellent rigidity for medium-to-heavy linear motion tasks.
This specific model is configured with a CB rear double clevis mount (fork), part number F-SC80CB, allowing the cylinder body to pivot during operation. The total extended body length is 482 mm (182 mm body length A + 300 mm stroke). It features an adjustable air cushion (28 mm length) to decelerate the piston smoothly at the end of its travel, reducing impact and noise.

Where the Airtac SC80 Standard Cylinder SC80X300CB Is Used
Agricultural Machinery
Operates chute diverters and hopper gates on harvesters and spreaders. The CB rear clevis mount allows the cylinder to pivot freely, accommodating the articulation of the linkage.
Conveyor Sorting Gates
Pivots a diverter arm on a high-speed sorting line. The 2513 N push force at standard shop air pressure easily handles the inertial load of a heavy steel gate.
Clamping & Welding Fixtures
Provides the powerful, controlled motion needed to close a heavy welding jig. The adjustable cushion ensures a soft stop, preventing vibration that could disturb the weld puddle.
Is the Airtac SC80 Standard Cylinder SC80X300CB the Right Cylinder?
For applications requiring a pivoting mount, the CB rear double clevis on this SC80X300 is an ideal choice, allowing angular movement. If your force requirement is slightly lower, stepping down to a 63 mm bore provides 1559 N of push force at 0.5 MPa; for significantly more force, a 100 mm bore delivers 3927 N. When replacing an existing cylinder, ensure a 5-point match: 80 mm bore, 300 mm stroke, PT1/8 port thread, the CB rear clevis mounting accessory, and the absence of a magnet.
With a 300 mm stroke, the rod is extended significantly. For applications with any side loading, an external guide system or a guided cylinder is strongly recommended to prevent bending stress on the 25 mm rod and premature bearing wear. The SC80 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 SC80X300CB FAQ
At the standard operating pressure of 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 increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X300CB is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop. If load holding is a safety requirement, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve in the circuit.
