About the Airtac SC50 Standard Cylinder SC50X140SN
The SC50X140SN is a 50 mm bore, 140 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod family. It generates 982 N of push force and 825 N of pull force when supplied with 0.5 MPa air, making it a capable mid-range actuator for clamping, pressing, and material-handling tasks. The 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth end-of-stroke deceleration.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors on the barrel, enabling simple position feedback without external brackets. The -N suffix specifies NBR (nitrile) seals, and the port thread is standard PT 1/4. With a body length of 150 mm, the total extended length is approximately 290 mm.

Where the Airtac SC50 Standard Cylinder SC50X140SN Is Used
Conveyor Diverter Gates
The 982 N push force at 0.5 MPa reliably actuates diverter gates and sorting paddles on packaging and logistics conveyors. The built-in magnet allows easy addition of end-of-stroke sensors to confirm gate position.
Component Clamping
Delivers consistent, controlled clamping force for CNC fixtures and assembly jigs. The NBR seals provide good wear resistance in typical workshop air conditions, and the adjustable cushion reduces impact noise.
Automated Pressing
Ideal for light pressing, staking, or riveting operations in automated cells. The 20 mm rod provides rigidity, and the magnetic piston enables precise stroke-end detection for cycle control.
Is the Airtac SC50 Standard Cylinder SC50X140SN the Right Cylinder?
Choose the SC50X140SN when your application needs roughly 980 N of force at standard plant pressure. If you require more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore delivers 628 N. This 140 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.
For replacement, match five key points: 50 mm bore, 140 mm stroke, PT 1/4 port thread, the built-in magnet (-S), and the NBR seal material. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. Ensure any external guides or mounts are aligned to prevent side-loading the rod bearing.
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 SC50X140SN FAQ
At 0.5 MPa (5 bar), the cylinder produces 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet in the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor grooves for contactless position sensing.
