About the Airtac SC50 Standard Cylinder SC50X320SN
The SC50X320SN is a 50 mm bore, 320 mm stroke double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke detection without external brackets. The NBR seal (-N) offers consistent performance with standard filtered air, and PT1/4 ports keep the pneumatic connections compact.

Where the Airtac SC50 Standard Cylinder SC50X320SN Is Used
Material Handling Gates
Actuates diverter gates on conveyor lines, using the 982 N push force to reliably redirect packages or components. The 320 mm stroke provides ample travel for wide chute openings.
Clamping & Assembly Jigs
Powers clamping fixtures in woodworking or metal fabrication cells. The built-in magnet allows sensors to confirm clamp engagement, ensuring cycle safety before machining starts.
Waste Compactor Ejectors
Drives an ejector plate in small baling or compacting machines, using the full 320 mm stroke to push compacted material clear of the chamber with consistent force.
Is the Airtac SC50 Standard Cylinder SC50X320SN the Right Cylinder?
For a 50 mm bore, this cylinder provides 982 N at 0.5 MPa. If your load requires more force, stepping up to a 63 mm bore (SC63) raises push force to 1559 N at the same pressure. For lighter, faster applications, a 40 mm bore (SC40) delivers 628 N. At 320 mm stroke, the 20 mm rod is robust for axial loads, but any significant side force requires an external linear guide or a guided cylinder to protect the rod bearing from bending and premature seal wear.
To replace an existing SC50X320SN, match five points: 50 mm bore, 320 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the NBR seal material. The basic mounting configuration uses the cylinder body for direct attachment.
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 SC50X320SN FAQ
At the standard 0.5 MPa operating pressure, the cylinder produces 982 N of push force and 825 N of pull force. At 0.7 MPa, push force increases to 1374 N. The maximum theoretical force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional mounting hardware.
