About the Airtac SC80 Standard Cylinder SC80X12.5
The SC80X12.5 is a compact-stroke variant in the AirTAC SC tie-rod cylinder family, providing a powerful 2513 N of push force at 0.5 MPa from its 80 mm bore. With a 12.5 mm stroke, this double-acting cylinder is ideal for precise clamping, ejecting, or short-travel positioning tasks where space is tight and a strong, immediate pneumatic response is required.
This model features a 25 mm diameter piston rod with M20x1.5 threads and PT3/8 ports. The short 12.5 mm stroke is a non-standard, made-to-order length for the SC80 bore, which typically starts at 25 mm standard strokes. Its adjustable air cushion (28 mm length) effectively decelerates the piston, protecting the end caps during high-cycle, short-throw operations.

Where the Airtac SC80 Standard Cylinder SC80X12.5 Is Used
High-Force Clamping
The 2513 N push force at 0.5 MPa makes this short-stroke cylinder perfect for heavy-duty workpiece clamping in machining centers or welding fixtures, where a compact actuator must deliver immediate, high holding pressure.
Precision Ejection
With its 12.5 mm stroke, the SC80X12.5 excels in part-ejection systems on stamping or injection molding lines, providing a powerful, repeatable push to separate finished components from dies or molds.
Diverter Gate Actuation
Use this cylinder to actuate diverter gates on conveyor systems. Its high force ensures reliable gate movement even with heavy product accumulation, while the short stroke enables fast cycle times for sorting applications.
Is the Airtac SC80 Standard Cylinder SC80X12.5 the Right Cylinder?
For applications needing slightly less force in a smaller footprint, the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. If your load requires a longer standard stroke, the SC80 bore supports standard strokes up to 1500 mm. This short-stroke unit is a direct replacement for an existing AirTAC SC80X12.5 tie-rod cylinder; ensure the replacement matches the 80 mm bore, 12.5 mm stroke, PT3/8 port thread, and basic mounting configuration.
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 SC80X12.5 FAQ
At the standard operating pressure of 0.5 MPa, the SC80X12.5 generates 2513 N of push force on extension and 2268 N of pull force on retraction. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
No, a 12.5 mm stroke is a non-standard, made-to-order length for the SC80 bore. The standard stroke range for the SC80 begins at 25 mm. This custom stroke is manufactured to your specification and is not typically available as an off-the-shelf stock item.
