About the Airtac SC80 Standard Cylinder SC80X850S
The AirTAC SC80X850S is a double-acting single-rod pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and 850 mm stroke, this model includes a built-in magnet (suffix -S) for mounting CMSG/DMSG/EMSG reed or solid-state sensors directly onto the tie-rod barrel, enabling precise end-of-stroke or mid-stroke position feedback.
This tie-rod cylinder features a 25 mm diameter piston rod with an M20x1.5 male knuckle thread and PT3/8 pneumatic ports. The adjustable air cushion at each end is 28 mm long, effectively decelerating the piston to reduce impact noise and vibration. The total extended body length is approximately 1032 mm, combining the 182 mm body length with the 850 mm stroke.

Where the Airtac SC80 Standard Cylinder SC80X850S Is Used
Material Handling & Sorting
The 850 mm stroke and sensor capability make this cylinder ideal for long-reach pushers and diverters on conveyor lines, where end-of-stroke confirmation is required for automated sorting.
Automated Assembly Fixtures
Provides a robust 2513 N clamping or pressing force at standard line pressure, with magnetic sensors verifying tool position in automated assembly cells.
Packaging & Palletizing
Suitable for case erectors and pallet dispensers where a long, controlled stroke is needed to move heavy packaging materials into place.
Is the Airtac SC80 Standard Cylinder SC80X850S the Right Cylinder?
For applications requiring position sensing, the SC80X850S is ready to accept CMSG/DMSG/EMSG switches that clamp directly to the barrel without additional brackets. When selecting a replacement, ensure a match across five key points: 80 mm bore, 850 mm stroke, PT3/8 port thread, the built-in magnet feature, and the basic mounting configuration. If your load requires more force, consider stepping up to the SC100 series, which provides 3927 N of push force at 0.5 MPa. For strokes of this length, be mindful of side loading; the 25 mm rod may require an external guide or a guided cylinder if the load is not purely axial to prevent rod bearing wear and bending.
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 SC80X850S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides a push force of 2513 N and a pull force of 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
Yes. The -S suffix indicates a built-in magnet along the barrel, which is specifically designed for use with AirTAC CMSG, DMSG, or EMSG series sensors. These sensors clamp directly onto the tie-rod barrel to detect piston position.
