About the Airtac SC80 Standard Cylinder SC80X400CA
The SC80X400CA is an 80 mm bore double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa (4523 N at 0.9 MPa). With a 400 mm stroke and a 25 mm diameter piston rod, this model is well-suited for medium-duty material handling and pressing tasks that require a pivoting mount.
This configuration features a CA rear single clevis mounting (part F-SC80CA), allowing the cylinder body to pivot during operation to accommodate angular motion. The cylinder uses an adjustable air cushion (28 mm length) to decelerate the piston smoothly, and the PT1/4 port thread is standard. The total body length A is 182 mm, giving an extended length of approximately 582 mm.

Where the Airtac SC80 Standard Cylinder SC80X400CA Is Used
Conveyor Diverters
The 2513 N push force at 0.5 MPa easily actuates heavy-duty diverter gates on wide conveyors. The rear clevis mount allows the cylinder to pivot as the gate swings, preventing rod binding.
Agricultural Equipment
Ideal for controlling chutes or hopper doors on harvesters and spreaders. The robust tie-rod design and TPU seals handle dusty, damp environments, while the clevis mount simplifies installation on pivoting linkages.
Clamping & Fixturing
Delivers up to 4523 N of clamping force at 0.9 MPa for welding jigs or assembly fixtures. The adjustable cushioning protects the fixture from impact damage during high-speed clamp cycles.
Is the Airtac SC80 Standard Cylinder SC80X400CA the Right Cylinder?
Select the SC80 when the 50 mm bore's 982 N (at 0.5 MPa) is insufficient for the load. If your application requires a stationary, non-pivoting mount, consider the basic or LB foot mount versions. For strokes of 400 mm, ensure the rod is not subjected to significant side loads; an external guide rail or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
For a direct replacement, match five key points: the 80 mm bore, the 400 mm stroke, the PT port thread, the CA rear single clevis mounting accessory, and the absence of a built-in magnet. This ensures dimensional and functional interchangeability with an existing AirTAC SC80X400CA unit.
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 SC80X400CA 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 reaches 4523 N. The theoretical maximum force at1.0 MPa is 513 kgf.
Yes, if your existing cylinder matches these specifications: an AirTAC SC series (tie-rod), 80 mm bore, 400 mm stroke, PT1/4 ports, a CA rear single clevis mount, and no built-in magnet. This is not an ISO 15552 cylinder, so it will not directly replace a profile cylinder with different mounting dimensions.
