About the Airtac SC80 Standard Cylinder SC80X550SN
The AirTAC SC80X550SN is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, scaling up to a robust 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 the 550 mm stroke, making it a reliable workhorse for medium-to-heavy linear motion tasks.
This specific configuration includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for precise, non-contact position feedback. The NBR seal material (-N suffix) offers reliable performance in standard industrial environments, while the PT port thread ensures straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X550SN Is Used
Material Handling & Sorting
Actuates diverter gates or pushers on conveyor lines. The 4523 N max force at 0.9 MPa handles heavy parcels, while the built-in magnet enables sensor-based end-of-stroke confirmation for automated sortation logic.
Clamping & Assembly Fixtures
Provides consistent clamping pressure for welding or assembly jigs. The adjustable cushion decelerates the clamp arm smoothly, preventing part damage, and the NBR seals are compatible with trace oils common in manufacturing cells.
Palletizing & Depalletizing
Drives the vertical lift axis on a light-duty palletizer. The550 mm stroke covers a full pallet layer height, and the magnetic piston allows for mid-stroke deceleration sensing to optimize cycle time.
Is the Airtac SC80 Standard Cylinder SC80X550SN the Right Cylinder?
When sizing, consider that the SC80 bore generates 2513 N at 0.5 MPa. If your application requires slightly less force, the SC63 series provides 1559 N, which may offer a more compact and cost-effective solution. For higher force demands, stepping up to the SC100 bore delivers 3927 N at the same pressure.
For this 550 mm stroke, the extended rod length increases the risk of bending under side loads. Always ensure the load is guided externally or consider using a guided cylinder if lateral forces are present. For a direct replacement, match this model's 80 mm bore, 550 mm stroke, PT port thread, basic mounting style, and the integrated magnet for sensor compatibility.

- ✓ 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 SC80X550SN FAQ
The theoretical push force at0.5 MPa (approx.73 psi) is2513 N. At the maximum operating pressure of0.9 MPa, it reaches4523 N. The pull force on the retract stroke is slightly lower at2268 N at0.5 MPa due to the rod area.
Yes. The '-S' in the model code confirms a built-in magnet is installed on the piston. This allows AirTAC's CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the cylinder's tie-rods for detecting piston position without additional brackets.
