About the Airtac SC80 Standard Cylinder SC80X820S
The SC80X820S is an 80 mm bore double-acting tie-rod cylinder with an extended 820 mm stroke and a built-in magnet for sensor mounting. At 0.5 MPa it generates 2513 N push force, scaling to 4523 N at the maximum 0.9 MPa operating pressure, making it a capable mid-range actuator for long-travel linear tasks.
This model uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. The 28 mm adjustable air cushion at each end decelerates the piston smoothly, while the body length A is 182 mm. The -S suffix equips the barrel with a magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod tube for reliable end-of-stroke detection.

Where the Airtac SC80 Standard Cylinder SC80X820S Is Used
Long-Reach Part Transfer
The 820 mm stroke pushes or pulls components across wide conveyor gaps. The built-in magnet lets DMSG sensors confirm full extension and retraction at each cycle.
Automated Panel Indexing
Moves large sheet-metal panels into a press brake or shear. The 2513 N force at 0.5 MPa handles heavy tooling, and the adjustable cushion protects the die from impact.
Pallet Dispenser Actuation
Drives the lifting carriage in a pallet magazine. The 28 mm cushion absorbs the kinetic energy of the stack, while CMSG sensors provide position confirmation to the PLC.
Is the Airtac SC80 Standard Cylinder SC80X820S the Right Cylinder?
Choose the SC80X820S when your application needs a long 820 mm stroke with sensor feedback. If the 2513 N push force at 0.5 MPa is marginal, stepping up to the SC100 bore provides 3927 N at the same pressure; if the stroke is shorter than needed, the SC63 delivers 1559 N in a more compact body.
For this 820 mm stroke, side loading on the 25 mm rod is a critical consideration. An unsupported long stroke can cause rod deflection and premature bearing wear. Fit an external linear guide or rod-alignment coupler to absorb transverse forces, and ensure the CMSG/DMSG/EMSG sensors are positioned to stop the stroke before the piston bottoms out hard. When replacing, match bore, stroke, PT3/8 port thread, the -S magnet option, and the basic mounting configuration.
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 SC80X820S FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At 0.7 MPa push rises to 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 means a magnet is built into the piston, so AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors clip directly onto the tie-rod barrel. Order sensors separately to match your controller input.
