About the Airtac SC50 Standard Cylinder SC50X220S
The AirTAC SC50X220S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa. Its 50 mm bore and 220 mm stroke suit medium-force pneumatic tasks where position sensing is required, thanks to the built-in magnet that accepts CMSG/DMSG/EMSG sensors directly on the barrel.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston at end-of-stroke to reduce impact. The SC50 body length A is 150 mm, giving a total extended length of approximately 370 mm for this 220 mm stroke configuration.

Where the Airtac SC50 Standard Cylinder SC50X220S Is Used
Conveyor Diverter Gates
The 220 mm stroke and 50 mm bore provide ample force to shift diverter gates on packaging or sorting conveyors. The built-in magnet enables end-of-stroke confirmation via reed sensors.
Clamping & Fixturing
With 982 N of force at 0.5 MPa, this cylinder is ideal for pneumatic clamping in machining fixtures. Magnetic piston sensing confirms the clamp is fully engaged before a cycle starts.
Material Lift Assistance
Use the SC50X220S in light-duty lifting or tilting mechanisms. The adjustable cushion protects the assembly from shock at the end of the 220 mm travel.
Is the Airtac SC50 Standard Cylinder SC50X220S the Right Cylinder?
Choose the SC50 when your application needs roughly 1000 N of push force from standard shop air. If you require more force, the SC63 bore provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 delivers 628 N. Always match replacement cylinders on five points: bore (50 mm), stroke (220 mm), PT1/4 port thread, the built-in magnet (-S suffix), and any mounting accessory. For strokes over 300 mm, consider external guides to protect the rod from side-load bending, but at 220 mm this model is well within standard unsupported rod limits for axial loads.
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 SC50X220S FAQ
At 0.5 MPa (5 bar) the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix in SC50X220S indicates a built-in magnet on the piston. This allows you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without external brackets.
