About the Airtac SC50 Standard Cylinder SC50X320S
The SC50X320S is a double-acting tie-rod cylinder with a 50 mm bore and 320 mm stroke, fitted with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed and solid-state sensors. At 0.5 MPa it generates 982 N pushing force and 825 N pulling force, rising to 1767 N push at the maximum operating pressure of 0.9 MPa.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, and the standard TPU/NBR seals give an operating range of -20 to +70 °C. The body length A is 150 mm, so the total extended length is approximately 470 mm.

Where the Airtac SC50 Standard Cylinder SC50X320S Is Used
Sensor-Monitored Part Transfer
The built-in magnet lets CMSG/DMSG sensors confirm end-of-stroke, making this cylinder ideal for pick-and-place or shuttle units where the controller must verify position before the next cycle.
Light Press & Clamping
With 982 N of push at standard shop air, the SC50X320S applies consistent clamping force on assembly fixtures, gluing jigs, or light-duty stamping nests.
Diverting & Sorting Gates
The 320 mm stroke provides enough travel to swing a diverter gate or flap on a packaging line, while the magnetic piston signals the gate position to the line PLC.
Is the Airtac SC50 Standard Cylinder SC50X320S the Right Cylinder?
Choose the SC50X320S for mid-range clamping, pressing, and transfer tasks where magnetic piston sensing is required. If you need more force, step up to the SC63 bore (1559 N push at 0.5 MPa); for a lighter, faster actuator, the SC40 delivers 628 N.
For this 320 mm stroke, avoid unsupported side loads that can bend the 20 mm rod or wear the bearing. Use an external linear guide or a guided cylinder if the load is not perfectly axial. When replacing an existing unit, match all five points: 50 mm bore, 320 mm stroke, PT1/4 ports, the basic (no bracket) mounting, and the -S magnet for sensor compatibility.
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 SC50X320S FAQ
At 0.7 MPa (7 bar) the SC50 bore generates 1374 N of pushing force and 825 N of pulling force, based on the official AirTAC thrust table. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N.
Yes. The -S suffix means a magnet is built into the piston, so CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel without any modification. A standard SC50X320 without the -S does not support barrel-mounted sensors.
