About the Airtac SC80 Standard Cylinder SC80X390S
The SC80X390S is an 80 mm bore, 390 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a substantial 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod. The total extended body length is approximately 572 mm, combining the 182 mm body length A with the 390 mm stroke.
This model includes a factory-installed -S magnet, allowing easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for precise end-of-stroke or mid-stroke position feedback. With a 28 mm adjustable air cushion at each end, it effectively decelerates moving loads, reducing impact noise and vibration. The standard PT1/4 port thread and TPU seals with an operating range of -20 to +70 °C make it a robust choice for general industrial automation.

Where the Airtac SC80 Standard Cylinder SC80X390S Is Used
Sorting Gate Actuation
The 390 mm stroke provides the long travel needed to fully extend a diverter gate on a wide conveyor line, while the built-in magnet sensors confirm gate position for reliable product sorting.
Clamping & Fixturing
Delivering up to4523 N of force at0.9 MPa, this cylinder is ideal for heavy-duty clamping of large workpieces in welding or machining fixtures, with sensor feedback ensuring the clamp is fully engaged.
Palletizer Pusher
Use the long390 mm stroke to push boxes or bags onto a pallet. The adjustable cushioning smoothly stops the high-inertia load, and the magnetic piston allows for multi-position sensor setup along the push stroke.
Is the Airtac SC80 Standard Cylinder SC80X390S the Right Cylinder?
For applications requiring slightly less force, the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa, while stepping up to the100 mm bore SC100 series offers3927 N. When using a390 mm stroke, always assess the potential for side loads on the extended rod; an external guide rail or rod alignment coupler is strongly recommended to prevent rod bending and premature bearing wear, especially at higher speeds. To ensure a correct replacement, match five key specifications:80 mm bore,390 mm stroke, PT1/8 port thread, the built-in magnet option(-S), and the basic mounting style. This cylinder is a direct replacement for another AirTAC SC80X390S or an identically configured tie-rod cylinder.
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 SC80X390S FAQ
At0.5 MPa operating pressure, this80 mm bore cylinder generates2513 N of push force and2268 N of pull force. The maximum theoretical push force at1.0 MPa is513 kgf.
Yes. The '-S' suffix in the model code SC80X390S indicates a built-in magnet in the piston. This allows you to directly clamp AirTAC CMSG, DMSG, or EMSG sensors onto the barrel's external tie-rod grooves to detect piston position without any additional brackets.
