About the Airtac SC80 Standard Cylinder SC80X815S
The SC80X815S delivers 2513 N of push force at 0.5 MPa and reaches 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust mid-range actuator for long linear moves. This model features an 80 mm bore with a 25 mm diameter piston rod and a 28 mm adjustable air cushion at each end to decelerate the mass smoothly.
A built-in magnet is factory-installed in the piston, so CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for non-contact position sensing. The 815 mm stroke is well within the 1500 mm maximum standard stroke for this bore, and the total extended body length is approximately 997 mm (182 mm body length A plus stroke).

Where the Airtac SC80 Standard Cylinder SC80X815S Is Used
Long-Stroke Part Transfer
Moves components 815 mm between conveyor lanes or workstations. The built-in magnet allows end-of-stroke confirmation with a CMSG sensor to interlock with downstream automation.
Automated Panel Tilter
Pushes large panels or sheets into a tilted position for assembly access. The 28 mm cushion absorbs the inertial energy of the panel at the end of the long stroke.
Pallet Dispenser Ejector
Ejects a single pallet from the bottom of a stack with an 815 mm push. The 25 mm rod provides the column strength needed for the extended reach without buckling under axial load.
Is the Airtac SC80 Standard Cylinder SC80X815S the Right Cylinder?
Choose the SC80 when your application needs more force than the SC63 (1559 N at 0.5 MPa) but does not require the bulk of the SC100 (3927 N at 0.5 MPa). For strokes above 300 mm like this 815 mm unit, confirm that the rod is not exposed to significant side loading; if side load is present, add an external guide rail or switch to a guided cylinder to protect the rod bearing from bending stress.
To replace an existing cylinder, match these five points exactly: 80 mm bore, 815 mm stroke, PT port thread (PT3/8), the basic mount configuration, and the -S magnet option for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X815S FAQ
At 0.7 MPa (7 bar) supply pressure, this 80 mm bore cylinder generates 3518 N of push force and 2268 N of pull force on the retract stroke. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without any additional brackets.
