About the Airtac SC80 Standard Cylinder SC80X620SN
The SC80X620SN is a double-acting pneumatic cylinder delivering 2513 N of push force and 2268 N of pull force at 0.5 MPa, scaling up to 4523 N at 0.9 MPa. Its 620 mm stroke is well within the 1500 mm maximum standard stroke for the 80 mm bore, making it a standard catalog item. The 25 mm diameter piston rod and 28 mm adjustable air cushion provide robust deceleration for mid-to-high speed applications.
This model includes a built-in magnet (suffix -S) for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel, enabling precise position feedback. The NBR seal (suffix -N) offers reliable sealing for standard industrial environments. With a PT1/8 port thread and a body length A of 182 mm, this genuine AirTAC cylinder is ready for immediate integration into automated machinery.

Where the Airtac SC80 Standard Cylinder SC80X620SN Is Used
Material Handling & Sorting
Pushes or diverts boxes and totes on conveyor lines. The 620 mm stroke provides ample reach across wide belts, and the built-in magnet allows for multi-position sensing to track diverter gate status.
Automated Assembly Pressing
Delivers up to 4523 N of force for pressing bearings, bushings, or clips. The adjustable cushion decelerates the tooling smoothly at the end of the 620 mm stroke, protecting parts and reducing cycle noise.
Pallet Dispensing & Stopping
Acts as a heavy-duty pallet stop or singulator. The 25 mm rod withstands impact, while the NBR seals and sensor capability support reliable operation in dusty warehouse conditions.
Is the Airtac SC80 Standard Cylinder SC80X620SN the Right Cylinder?
Select the SC80 bore when your application requires between 2513 N and 4523 N of force. If your load demands more, step up to the SC100 bore, which provides 3927 N at 0.5 MPa. For lighter, more compact requirements, the SC63 bore offers 1559 N at the same pressure. Always match the bore, 620 mm stroke, PT port thread, and the -S magnet option when replacing an existing unit.
For this 620 mm stroke, carefully evaluate side-loading conditions. Long, unsupported piston rods are susceptible to bending under lateral forces. If the load is not guided externally, consider adding an external guide rail or switching to a guided cylinder configuration to protect the rod bearing and ensure long service life.
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 SC80X620SN FAQ
At 0.7 MPa operating pressure, the SC80 bore generates a theoretical push force of 3518 N. The pull force on the retract stroke at the same pressure is 3175 N. Always apply a safety factor for real-world dynamic loads.
Yes. The -S suffix in SC80X620SN indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing without any additional brackets.
