About the Airtac SC80 Standard Cylinder SC80X780S
The SC80X780S is a double-acting pneumatic tie-rod cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). Its 780 mm stroke suits long-reach material transfer and actuation tasks, with a 25 mm diameter piston rod providing robust linear guidance.
A built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The adjustable air cushion at each end (28 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact at speeds up to 800 mm/s.

Where the Airtac SC80 Standard Cylinder SC80X780S Is Used
Long-Reach Part Transfer
The 780 mm stroke moves components between distant conveyor stations, with magnetic sensors confirming full extension and retraction for interlock safety.
Palletising Pusher
Pushes boxes or trays onto pallets with 2513 N of force at standard shop air. The built-in magnet enables end-of-stroke detection without external brackets.
Automated Assembly Indexing
Indexes fixtures across a 780 mm work envelope. Adjustable cushioning protects tooling at both ends, while the -S magnet provides position feedback to the PLC.
Is the Airtac SC80 Standard Cylinder SC80X780S the Right Cylinder?
For applications needing more force, the SC100 bore delivers 3927 N at 0.5 MPa; for a lighter, more compact solution, the SC63 bore provides 1559 N. Always match bore, 780 mm stroke, PT1/4 port thread, and the -S magnet when replacing an existing SC cylinder.
At 780 mm stroke, the extended rod length increases the risk of side-load bending. Use an external guide rail or a guided cylinder if the load is not perfectly axial, or consider stepping up to the SC100 bore for a stiffer 25 mm rod assembly.
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 SC80X780S FAQ
At 0.7 MPa operating pressure, the SC80X780S generates 3518 N of push force and 2268 N of pull force on the retract stroke, based on the 80 mm bore and 25 mm rod diameter.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel tie-rods for contactless position sensing.
