About the Airtac SC50 Standard Cylinder SC50X400SN
The AirTAC SC50X400SN is a double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). Its 400 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making it a stock-configuration actuator for medium-reach linear tasks.
This model includes a built-in magnet (-S) so CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the barrel for contactless position sensing. The -N suffix specifies NBR (nitrile) seals, suited for general industrial air service. The 20 mm diameter piston rod and PT1/4 port threads handle standard pneumatic plumbing, while the 21 mm adjustable air cushion smooths end-of-stroke deceleration.

Where the Airtac SC50 Standard Cylinder SC50X400SN Is Used
Package Sorting Gate
Actuates a diverter gate on a medium-speed conveyor line. The 400 mm stroke provides enough reach to push cartons onto a branch lane, while the magnetic piston lets CMSG sensors confirm gate open/closed position for the PLC.
Automated Clamping Fixture
Powers a horizontal clamp on a CNC machining centre. The 982 N force at shop air pressure securely holds a workpiece during milling. The built-in magnet enables end-of-clamp verification, preventing cycle-start without confirmed part clamping.
Pallet Stop & Release
Drives a heavy-duty pallet stop in a gravity roller conveyor. The 50 mm bore provides the force to halt a loaded pallet, and the 400 mm stroke lifts the stop blade high enough to clear the pallet runner. NBR seals handle the dusty warehouse environment reliably.
Is the Airtac SC50 Standard Cylinder SC50X400SN the Right Cylinder?
Choose the SC50 bore when your application requires between 982 N and 1767 N of push force. If you need more force, step up to the SC63 (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 delivers 628 N. For strokes of 300 mm or more like this 400 mm unit, watch for side loading—the 20 mm rod can bend under off-axis force. Use an external linear guide or a guided cylinder if the load is not perfectly aligned.
To match this cylinder for replacement, verify five points: 50 mm bore, 400 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor mounting, and the basic (no-bracket) mounting style. The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC tie-rod units of the same configuration.
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 SC50X400SN FAQ
At 0.7 MPa (7 bar), the SC50 bore generates a theoretical push force of 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa. The maximum operating force at 0.9 MPa is 1767 N push.
Yes. The -S suffix in the model code SC50X400SN means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's tie-rod slots to detect piston position without any additional brackets.
