About the Airtac SC50 Standard Cylinder SC50X420S
The SC50X420S is a double-acting pneumatic cylinder with a 50 mm bore and 420 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke automation tasks.
This model includes the -S suffix, equipping the cylinder with a built-in magnet. This allows for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise, non-contact position sensing without external brackets. The standard TPU seals ensure reliable operation in ambient temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X420S Is Used
Material Stop & Diverter
The 420 mm stroke and built-in magnet for sensor feedback make this cylinder ideal for actuating gates or diverters on conveyor lines, confirming position at each end of travel.
Automated Clamping
With 982 N of force at 0.5 MPa, it provides consistent clamping pressure for woodworking or light metal fabrication jigs, where mid-range force and reliable position sensing are critical.
Packaging Pusher
Use the SC50X420S to push cartons or products onto a palletizing station. The magnet allows for easy integration of sensors to verify the pusher has fully retracted before the next cycle.
Is the Airtac SC50 Standard Cylinder SC50X420S the Right Cylinder?
Select the SC50 for applications needing up to 982 N of push force at standard plant pressure. If your load requires more thrust, consider stepping up to the SC63 bore, which provides 1559 N at 0.5 MPa. For lighter, more compact needs, the SC40 offers 628 N. With a 420 mm stroke, ensure the rod is protected from side loads; an external guide or a guided cylinder is recommended to prevent rod bearing wear and bending when the load is not purely axial. For a direct replacement, match the 50 mm bore, 420 mm stroke, PT port thread, and the -S magnet option.
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 SC50X420S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. These values are based on the cylinder's 50 mm bore and 20 mm rod diameter.
Yes. The -S suffix in the model code SC50X420S indicates a built-in magnetic piston. You can directly clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the cylinder barrel's tie-rod slots to detect end-of-stroke or intermediate positions.
