About the Airtac SC50 Standard Cylinder SC50X156S
The AirTAC SC50X156S is a double-acting tie-rod cylinder with a 50 mm bore and 156 mm stroke, 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 linear motion tasks.
The integrated magnet (suffix -S) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. Standard PT1/4 ports and TPU seals rated for -20 to +70 °C make this a practical, sensor-ready actuator for general industrial automation.

Where the Airtac SC50 Standard Cylinder SC50X156S Is Used
Part Stops & Diverters
The 156 mm stroke and sensor-ready magnet make this cylinder ideal for actuating part stops or lane diverters on packaging and assembly conveyors, with precise end-of-stroke confirmation.
Clamping & Pressing
With 982 N of push force at 0.5 MPa, the SC50X156S provides consistent clamping pressure for drilling, welding, or gluing fixtures, where magnetic sensors verify the clamp is fully engaged.
Gate & Door Actuation
Use this cylinder to open and close small safety gates or hopper doors. The built-in magnet enables interlock sensing to confirm the gate position before allowing the next machine cycle.
Is the Airtac SC50 Standard Cylinder SC50X156S the Right Cylinder?
Choose the SC50 when your application needs around 982 N of push force at 0.5 MPa. If you require more force, step up to the SC63 bore (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 bore offers 628 N. This 156 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.
For replacement, match five points: 50 mm bore, 156 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting style. Always verify the tie-rod body length (A=150 mm) and overall extended length (approx. 306 mm) fit your existing machine envelope.
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 SC50X156S FAQ
At 0.5 MPa (5 bar), 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 reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in SC50X156S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without any additional brackets.
