About the Airtac SC80 Standard Cylinder SC80X260S
The AirTAC SC80X260S is a double-acting single-rod pneumatic cylinder with an 80 mm bore and 260 mm stroke, delivering a push force of 2513 N at 0.5 MPa (4523 N at the maximum operating pressure of 0.9 MPa). The built-in magnet (-S suffix) allows CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the tie-rod barrel for contactless position sensing, simplifying automation integration.
With a 25 mm diameter piston rod and PT3/8 ports, this model includes a 28 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 182 mm, giving a total extended length of approximately 442 mm. Operating on filtered air from 0.15 to 1.0 MPa, the SC80X260S uses standard TPU/NBR seals for a temperature range of -20 to +70 °C and supports speeds of 30-800 mm/s.

Where the Airtac SC80 Standard Cylinder SC80X260S Is Used
Conveyor Stop & Divert
The 2513 N push force at 0.5 MPa reliably stops or diverts medium-weight packages on belt conveyors. The built-in magnet enables end-of-stroke sensing to sequence gates without external brackets.
Clamping & Fixturing
Delivers 4523 N of clamping force at 0.9 MPa for holding workpieces during machining or welding. The adjustable cushion reduces impact, protecting both the fixture and the cylinder over millions of cycles.
Palletising Pusher
With a 260 mm stroke, this cylinder pushes boxes or layers onto a pallet. The magnetic piston allows CMSG sensors to confirm full extension and retraction, preventing incomplete cycles in automated palletisers.
Is the Airtac SC80 Standard Cylinder SC80X260S the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of push force; if you require less, stepping down to the SC63 bore provides 1559 N at 0.5 MPa, while stepping up to the SC100 bore offers 3927 N at 0.5 MPa. This 260 mm stroke is within the standard range for the 80 mm bore, which extends up to 1500 mm.
For strokes of 300 mm or more, always evaluate side-load conditions—long unsupported rods can bend under lateral forces. For this 260 mm stroke, an external guide or a guided cylinder is still recommended if side loads are present. When replacing an existing cylinder, match five points: 80 mm bore, 260 mm stroke, PT3/8 port thread, the basic mounting style, and the -S magnet for sensor compatibility.
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 SC80X260S 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, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact end-of-stroke detection.
