About the Airtac SC50 Standard Cylinder SC50X80S
The SC50X80S is a 50 mm bore double-acting pneumatic cylinder with an 80 mm stroke and a factory-installed magnet, delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and M16x1.5 male knuckle thread provide solid alignment for medium-duty linear tasks, while the 21 mm adjustable air cushion at each end decelerates the piston quietly.
This tie-rod cylinder includes the -S magnet option, so reed or solid-state sensors (CMSG, DMSG, EMSG) clip directly onto the barrel for rod-position feedback without extra brackets. The body length A is 150 mm, giving a compact total extended length of approximately 230 mm for installations where space is tight.

Where the Airtac SC50 Standard Cylinder SC50X80S Is Used
Sensor-Monitored Clamping
The built-in magnet lets CMSG/DMSG sensors confirm clamp closure, making the SC50X80S ideal for automated welding or assembly fixtures where stroke-end verification is required.
Part Stops & Diverters
At 982 N push force, this cylinder reliably raises a stop gate or swings a diverter arm on a packaging conveyor, with sensor feedback signaling the gate position to the PLC.
Press-Fit & Forming Tools
Delivering 1767 N at 0.9 MPa, the SC50X80S handles light press-fit insertions and forming operations, while the adjustable cushion protects tooling from impact damage.
Is the Airtac SC50 Standard Cylinder SC50X80S the Right Cylinder?
The 50 mm bore suits many clamping, pressing, and transfer applications. If you need more force, stepping up to the 63 mm bore raises push force to 1559 N at 0.5 MPa; if 50 mm is oversized, the 40 mm bore offers 628 N. Always match replacement cylinders on five points: bore, stroke, PT port thread, basic mounting (no accessory bracket on this code), and the -S magnet for sensor compatibility.
For strokes of 300 mm and above, consider an external guide or guided cylinder to protect the rod from side-load bending, but at 80 mm this model is inherently stiff.
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 SC50 Standard Cylinder SC50X80S FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force rises to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N.
Yes. The -S suffix indicates a built-in magnetic piston, so CMSG (reed) and DMSG/EMSG (solid-state) sensors mount directly onto the barrel tie-rods to detect rod position.
