About the Airtac SC80 Standard Cylinder SC80X940S
The SC80X940S is an 80 mm bore double-acting pneumatic cylinder with a 940 mm stroke, delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration for mid-to-heavy linear motion tasks.
This model includes the -S suffix, equipping the tie-rod barrel with a built-in magnet. This allows easy clamping of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the body for contactless position sensing, simplifying automation integration without external brackets.

Where the Airtac SC80 Standard Cylinder SC80X940S Is Used
Long-Stroke Part Transfer
The 940 mm reach moves components between distant conveyor stations or into multi-level assembly jigs, with sensors confirming end-of-travel at each shift.
Pallet Layer Forming
Pushes rows of boxes or bags onto a pallet layer table. The 2513 N force at standard line pressure handles stacked product weight reliably.
Automated Glue or Sealant Bead
Drives a dispensing head across a long workpiece. The magnetic piston allows precise speed monitoring via DMSG sensors for consistent bead profiles.
Is the Airtac SC80 Standard Cylinder SC80X940S the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 63 mm bore SC63 series offers 1559 N. At a 940 mm stroke, the rod is fully extended well beyond the 182 mm body length. Ensure the rod is not subjected to side loading; for unsupported long strokes, pair the cylinder with an external linear guide or consider a guided actuator to prevent rod bearing wear and bending.
When replacing this cylinder, match five key points: 80 mm bore, 940 mm stroke, PT1/8 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting style. This is a genuine AirTAC tie-rod cylinder, which is shorter than an ISO 15552 profile and not dimensionally interchangeable with those types.
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 SC80X940S FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N. The pull force on the retract stroke at the same pressure is 3175 N, accounting for the 25 mm rod area.
Yes. The -S suffix means this cylinder has a built-in magnet. You can directly mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors on the barrel's sensor groove to detect piston position without any additional mounting hardware.
