About the Airtac SC50 Standard Cylinder SC50X200SN
The SC50X200SN is a 50 mm bore, 200 mm stroke double-acting tie-rod cylinder equipped with a built-in magnet and NBR seals. It generates 982 N of push force and 825 N of pull force when operated at 0.5 MPa, making it a reliable mid-range actuator for general industrial automation.
This model features 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 basic body length A is 150 mm. The -S suffix indicates a magnet is embedded in the piston, allowing CMSG/DMSG/EMSG sensors to be mounted directly on the tie-rod barrel for non-contact position sensing.

Where the Airtac SC50 Standard Cylinder SC50X200SN Is Used
Package Diverting
Actuates a diverter gate on a conveyor line. The 982 N push force at 0.5 MPa reliably shifts cardboard boxes and lightweight packages, while the built-in magnet provides end-of-stroke confirmation to the PLC.
Clamping & Fixturing
Applies consistent clamping pressure to hold parts during drilling or welding. The NBR seals offer good wear resistance in oily workshop air, and the adjustable cushion reduces vibration transfer to the fixture.
Hopper Gate Control
Opens and closes a slide gate on a seed or grain hopper. The double-acting design ensures positive opening and closing under load, and the magnetic piston allows easy integration of sensors to monitor gate position remotely.
Is the Airtac SC50 Standard Cylinder SC50X200SN the Right Cylinder?
Choose the SC50 when your application needs around 982 N of force at standard plant air pressure. If you require more force, stepping up to the SC63 delivers 1559 N at the same 0.5 MPa. For lighter, faster cycles, the SC40 provides 628 N. To ensure a drop-in replacement, match five key points: 50 mm bore, 200 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style. The NBR seal material is specified for standard temperature ranges.
At a 200 mm stroke, the 20 mm rod is well-supported for axial loads. If your application involves any side loading, even at this moderate stroke, an external guide rail or a guided cylinder is recommended to protect the rod bearing and seals from premature wear and bending.
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 SC50X200SN FAQ
At the standard operating pressure of 0.5 MPa, this cylinder provides 982 N of push force on extension and 825 N of pull force on retraction. At the maximum operating pressure of 0.9 MPa, the push 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 is fitted to the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel for accurate, non-contact end-of-stroke detection.
