About the Airtac SC80 Standard Cylinder SC80X1140S
The AirTAC SC80X1140S is a double-acting single-rod pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). Its 80 mm bore and 1140 mm stroke suit long-travel linear applications where magnetic piston sensing is required.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke or mid-position detection. The 25 mm diameter rod, 28 mm adjustable air cushion, and PT3/8 port thread are standard for the 80 mm bore. Body length A is 182 mm, giving an extended length of approximately 1322 mm.

Where the Airtac SC80 Standard Cylinder SC80X1140S Is Used
Long-Reach Part Transfer
Moves components across wide conveyor gaps or between distant stations, with magnetic sensors confirming full extension and retraction.
Automated Gluing & Dispensing
Provides the extended linear stroke for adhesive or sealant dispensing heads, where the -S magnet signals the controller at each end of the bead.
Pallet Stop & Divert
Acts as a long-stroke stop or diverter arm in pallet-handling systems, using sensor feedback to sequence with lift tables and conveyors.
Is the Airtac SC80 Standard Cylinder SC80X1140S the Right Cylinder?
For higher force, step up to the SC100 bore (3927 N at 0.5 MPa); for a more compact build, the SC63 provides 1559 N. At 1140 mm stroke, side-load management is critical—fit external guide rails or a guided cylinder to protect the rod bearing from bending moments. To replace an existing SC80X1140S, match bore (80 mm), stroke (1140 mm), PT3/8 port, the -S magnet option, and basic mounting.
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 SC80X1140S FAQ
At 0.5 MPa the cylinder pushes with 2513 N; at 0.7 MPa it delivers 3518 N, and at the maximum operating pressure of 0.9 MPa it 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, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped onto the tie-rod barrel for contactless position sensing.
