About the Airtac SC80 Standard Cylinder SC80X265S
The SC80X265S is an 80 mm bore double-acting pneumatic cylinder with a 265 mm stroke, factory-equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed and solid-state sensors. At 0.5 MPa it generates 2513 N pushing force and 2268 N pulling force, rising to 4523 N push at the maximum operating pressure of 0.9 MPa.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The adjustable air cushion at each end is 28 mm long, and the tie-rod body length A is 182 mm, giving a total extended length of approximately 447 mm. The standard TPU/NBR seals suit an operating temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X265S Is Used
Conveyor Sorting Gate
The 265 mm stroke and 2513 N push force at 0.5 MPa reliably actuate a diverter gate on a packaging conveyor. The built-in magnet allows end-of-stroke sensors to confirm gate position for the line controller.
CNC Clamp & Unclamp
Delivers consistent clamping force for a fixture on a machining centre. The -S magnet enables electronic verification that the clamp is fully open before a robot loads the next part.
Pallet Stop / Lift
Powers a pallet stop on a gravity roller lane. The 80 mm bore provides ample force to halt a loaded pallet, and the sensor confirms the stop is retracted, clearing the lane.
Is the Airtac SC80 Standard Cylinder SC80X265S the Right Cylinder?
Choose the SC80X265S when your application needs the force capacity of an 80 mm bore – 2513 N at 0.5 MPa – and the convenience of sensor feedback via the built-in magnet. If your load is lighter, stepping down to a 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For heavier loads, the 100 mm bore provides 3927 N at the same pressure.
At 265 mm stroke, this cylinder is within the standard stroke range for the 80 mm bore. For a direct replacement, match five points: 80 mm bore, 265 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting configuration. Always use an external guide or a guided cylinder if the rod will experience significant side loads, as a tie-rod cylinder is designed for axial force.
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 SC80X265S 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.
Yes. The -S suffix in the model code indicates a built-in magnet is installed inside the piston. This allows you to clamp standard AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel tie-rods to detect piston position without any additional brackets.
