About the Airtac SC80 Standard Cylinder SC80X120S
The SC80X120S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 120 mm stroke. It delivers a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod with M20x1.5 threads.
This model includes the built-in magnet suffix -S, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The cylinder body length A is 182 mm, and the standard PT1/8 ports and adjustable air cushion ensure smooth deceleration in automation tasks.

Where the Airtac SC80 Standard Cylinder SC80X120S Is Used
Conveyor Diverter Gates
The 120 mm stroke and 2513 N push force at 0.5 MPa reliably actuate diverter gates on medium-duty package handling conveyors, with the built-in magnet providing end-of-stroke confirmation.
Clamping & Fixturing
Delivers controlled, repeatable clamping force for CNC machining fixtures. The adjustable cushion minimizes vibration at the end of the 120 mm stroke, protecting the workpiece and tooling.
Press-Fit Assembly
Ideal for light press-fit operations in automated assembly lines. The 4523 N maximum force at 0.9 MPa provides ample power for inserting bearings or bushings into housings.
Is the Airtac SC80 Standard Cylinder SC80X120S the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of push force. If your load requires less force, stepping down to the 63 mm bore provides 1559 N at 0.5 MPa, reducing air consumption. For higher force demands, the 100 mm bore offers 3927 N at the same pressure.
To ensure a drop-in replacement, match five key points: the 80 mm bore, 120 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. The 25 mm rod is robust, but for strokes over 300 mm or applications with side load, always consider an external guide or a guided cylinder to prevent rod bearing damage.
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 SC80X120S FAQ
At 0.7 MPa operating pressure, the SC80X120S cylinder produces a theoretical push force of 3518 N and a pull force of 2268 N. These values are based on the 80 mm bore and 25 mm rod diameter.
Yes. The -S suffix in the model code SC80X120S indicates a built-in magnet on the piston. This allows you to directly mount AirTAC CMSG, DMSG, or EMSG series sensors on the cylinder barrel to detect piston position without any additional brackets.
