About the Airtac SC80 Standard Cylinder SC80X135SN
The SC80X135SN is an 80 mm bore, 135 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers a push force of 2513 N at 0.5 MPa and reaches 4523 N at the maximum operating pressure of 0.9 MPa, making it a strong mid-range actuator for industrial automation tasks.
This model features a built-in magnet (-S suffix) that allows CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for precise end-of-stroke detection. The NBR seal (-N suffix) provides reliable sealing for standard temperature environments, and the 25 mm diameter piston rod with M20x1.5 thread offers robust connection for tooling.

Where the Airtac SC80 Standard Cylinder SC80X135SN Is Used
Material Handling Gates
The 2513 N push force at 0.5 MPa easily actuates diverter gates and stops on conveyor lines, with the 135 mm stroke providing ample travel for medium-width packages.
Clamping & Fixturing
Delivers consistent clamping pressure for CNC machining fixtures. The built-in magnet allows sensor confirmation of clamp engagement before the cycle starts.
Press & Assembly Tools
Suitable for light-duty assembly presses requiring a controlled 135 mm stroke. The NBR seals handle oiled compressed air commonly found in manufacturing plants.
Is the Airtac SC80 Standard Cylinder SC80X135SN the Right Cylinder?
For applications needing slightly less force, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. If higher force is required, stepping up to the 100 mm bore SC100 series delivers 3927 N at the same pressure. Always match the bore, 135 mm stroke, PT port thread, and the -S magnet option when replacing an existing SC80 cylinder.
With a stroke of 135 mm, this cylinder operates well within the standard range. Ensure the load is guided externally if any side forces are present, as the piston rod bearing is designed for axial loads. The built-in magnet simplifies adding position feedback without external brackets.
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 SC80X135SN FAQ
At 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.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to mount AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel to detect end-of-stroke positions without any additional mounting hardware.
