About the Airtac SC80 Standard Cylinder SC80X370S
The SC80X370S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 370 mm stroke. It generates a substantial push force of 2513 N at 0.5 MPa, rising to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This model includes the factory-fitted -S magnet, embedding a magnetic ring on the piston so that CMSG, DMSG, or EMSG reed and solid-state sensors can be directly mounted on the barrel for reliable end-of-stroke detection. The adjustable air cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly, protecting the end caps during high-cycle operation.

Where the Airtac SC80 Standard Cylinder SC80X370S Is Used
Sensor-Monitored Clamping
The built-in magnet allows CMSG/DMSG sensors to confirm clamp position in automated welding or assembly fixtures, ensuring the 2513 N clamping force is applied before the next cycle starts.
Part Transfer with Feedback
Ideal for a 370 mm linear transfer unit on a packaging line, where the magnetic piston signals the PLC that the pusher has fully extended or retracted, enabling precise timing control.
Automated Press-Fit Station
Delivers up to 4523 N of force at 0.9 MPa for light press-fit operations. The sensor confirms end-of-stroke, providing a simple go/no-go signal for quality assurance.
Is the Airtac SC80 Standard Cylinder SC80X370S the Right Cylinder?
Choose the SC80X370S when your application requires sensor feedback from a cylinder in the 2500 N force class. If you need higher force, stepping up to the SC100 bore provides 3927 N at the same 0.5 MPa pressure; for a lighter, more compact solution, the SC63 delivers 1559 N. Always match the replacement cylinder across five points: bore, stroke, port thread (PT), the built-in magnet (-S), and the basic mounting style.
At a 370 mm stroke, the 25 mm rod is extended significantly. Avoid direct side loading on the rod end; if the load is not perfectly guided, use an external linear guide or consider a guided cylinder to prevent rod bending and premature bearing wear.
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 SC80X370S FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 2513 N push force and 2268 N pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
Yes. The '-S' suffix in the model code SC80X370S indicates a built-in magnetic piston. This allows AirTAC's CMSG (reed) and DMSG/EMSG (solid-state) sensors to be band-clamped directly onto the barrel body without any additional brackets.
