About the Airtac SC50 Standard Cylinder SC50X140S
The SC50X140S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (up to 1767 N at 0.9 MPa). Its 140 mm stroke suits medium-reach clamping, pressing, and sorting tasks. The built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for non-contact position sensing.
This 50 mm bore model uses a 20 mm diameter piston rod with M16x1.5 threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at stroke end, reducing impact noise. The body length A is 150 mm, giving a total extended length of approximately 290 mm.

Where the Airtac SC50 Standard Cylinder SC50X140S Is Used
Automated Clamping
The 140 mm stroke and 982 N force at 0.5 MPa suit jig and fixture clamping in CNC machining cells, with magnetic sensors confirming clamp/unclamp position.
Part Sorting & Diverting
Pneumatic diverters and sortation gates benefit from the sensor-ready design, allowing precise confirmation of gate position at each cycle.
Packaging Press Operations
Delivers consistent pressing force for carton sealing or light assembly presses, where the compact tie-rod body fits into tight machine frames.
Is the Airtac SC50 Standard Cylinder SC50X140S the Right Cylinder?
For higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for a lighter, more compact option, the 40 mm bore provides 628 N. The -S suffix equips this cylinder with a magnet, so reed or solid-state sensors can be added for end-of-stroke or mid-stroke detection. When replacing, match bore (50 mm), stroke (140 mm), PT port thread, basic mounting, and the magnet option to ensure 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 SC50X140S FAQ
At 0.5 MPa, the push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel for contactless position detection.
