About the Airtac SC80 Standard Cylinder SC80X50CB
The SC80X50CB is an 80 mm bore, 50 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod with M20x1.5 male threads. The 50 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a compact, high-force solution for short linear movements.
This model is factory-configured with a rear double clevis (CB) mount, part F-SC80CB, which provides a pivoting anchor point at the cap end to accommodate angular misalignment during actuation. The cylinder body measures 182 mm (dimension A), resulting in a total extended length of approximately 232 mm. It uses standard PT1/8 ports and TPU seals for operation in ambient temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X50CB Is Used
Agricultural Implement Linkage
The rear clevis mount and high force output make this cylinder ideal for actuating pivot arms, chutes, or gates on agricultural machinery where the cylinder body must swing through an arc.
Clamping & Fixturing
Delivers a powerful, short stroke for heavy-duty workpiece clamping in machining centers or welding fixtures. The double clevis allows the cylinder to self-align, preventing rod side-loading.
Diverter Gate Actuation
Provides the rapid, high-force push needed to shift a diverter gate on a conveyor line. The pivoting CB mount simplifies installation in tight spaces where a fixed foot mount would bind.
Is the Airtac SC80 Standard Cylinder SC80X50CB the Right Cylinder?
For applications requiring slightly less force in a more compact body, stepping down to the 63 mm bore (1559 N at 0.5 MPa) may be suitable. If higher force is needed, the 100 mm bore provides 3927 N at the same pressure. The 50 mm stroke on this 80 mm bore is very short, so rod buckling is not a concern, but always ensure the load is guided if any side forces are present.
When replacing an existing cylinder, match five key points: 80 mm bore, 50 mm stroke, PT port thread, rear CB double clevis mounting, and the absence of a magnet. This SC series is a tie-rod design 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 SC80X50CB 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 SC80X50CB is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. The piston can drift or drop under load. For load-holding applications, you must add an external pilot-operated check valve or a mechanical rod lock.
