About the Airtac SC50 Standard Cylinder SC50X390S
The SC50X390S is a tie-rod double-acting cylinder with a 50 mm bore and 390 mm stroke, delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa max operating pressure). Its 20 mm diameter rod and 21 mm adjustable air cushion provide smooth deceleration for mid-stroke positioning tasks.
This model includes the -S suffix, integrating a magnet into the piston. This allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing, simplifying automation integration without external brackets.

Where the Airtac SC50 Standard Cylinder SC50X390S Is Used
Conveyor Diverters
The 390 mm stroke and magnetic piston sensing allow reliable product diverting on packaging lines, with sensors confirming gate position at each end of travel.
Automated Assembly
Pushes components into fixtures with 982 N at 0.5 MPa. The built-in magnet enables precise mid-stroke sensing for pick-and-place or press-fit verification.
Material Handling
Operates lift tables or tilt mechanisms with a 390 mm travel. The adjustable cushion absorbs impact at the end of stroke, protecting the structure during rapid cycling.
Is the Airtac SC50 Standard Cylinder SC50X390S the Right Cylinder?
For applications needing slightly less force, the 40 mm bore SC40 series provides 628 N at 0.5 MPa. If higher force is required, stepping up to the 63 mm bore delivers 1559 N. At a 390 mm stroke, the rod is fully supported within the standard stroke limit (max 1200 mm for bore 50), but if side loads are present, consider an external linear guide to protect the rod bearing from bending moments. When replacing an existing unit, match bore, stroke, PT port thread, the magnetic piston (-S), and mounting accessories exactly to ensure dimensional compatibility with another AirTAC SC tie-rod cylinder.
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 SC50X390S FAQ
At 0.7 MPa the theoretical push force is 1374 N. The maximum operating force at 0.9 MPa is 1767 N. Always apply a safety factor for real dynamic loads.
Yes. The -S suffix indicates a built-in magnetic piston. You can mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the cylinder barrel to detect piston position.
