About the Airtac SC80 Standard Cylinder SC80X50S
The SC80X50S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, pairing an 80 mm bore with a compact 50 mm stroke. At 0.5 MPa it generates 2513 N of push force, and at the maximum operating pressure of 0.9 MPa the thrust rises to 4523 N, driven by a 25 mm diameter piston rod.
This model includes the factory-fitted -S magnet, embedding a magnetic ring in the piston so that CMSG, DMSG, or EMSG reed and solid-state sensors can be clamped directly onto the barrel. The standard TPU seals give an operating range of -20 to +70 °C, and the PT1/8 ports connect to common pneumatic fittings. The body length A is 182 mm, giving a compact extended length of approximately 232 mm.

Where the Airtac SC80 Standard Cylinder SC80X50S Is Used
End-of-Stroke Sensing
The built-in magnet lets you mount CMSG/DMSG sensors directly on the barrel to confirm piston position in automated sequences, ideal for pick-and-place or ejector stations.
Short-Stroke Clamping
With 2513 N of force at 0.5 MPa, this 50 mm stroke unit is well suited to clamping fixtures, light press tools, or holding workpieces during machining.
Compact Machine Integration
The short 232 mm extended length fits easily into tight machine envelopes, making it a good match for sub-assembly stations where space is limited.
Is the Airtac SC80 Standard Cylinder SC80X50S the Right Cylinder?
Choose the SC80 bore when your load needs more force than the SC63 can supply—the SC63 delivers 1559 N push at 0.5 MPa, while the SC80 steps up to 2513 N. If your application requires even higher force, the SC100 bore offers 3927 N at the same pressure. The 50 mm stroke is well within the standard range, so lead times remain short.
For replacement, match five points: 80 mm bore, 50 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style. If you are adding external guides or supporting a side load, ensure the rod bearing is not subjected to bending moments beyond the 25 mm rod’s capacity.
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 SC80X50S FAQ
At 0.5 MPa the push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force 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, making the barrel compatible with AirTAC CMSG, DMSG, and EMSG series sensors. Simply clamp the sensor onto the barrel tie-rod groove to detect piston position.
