About the Airtac SC50 Standard Cylinder SC50X50N
The SC50X50N is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a capable mid-bore actuator for short-stroke clamping and pressing tasks. Its 50 mm stroke is built on a 150 mm body length, yielding a compact 200 mm total extended length with a 20 mm diameter piston rod and M16x1.5 rod thread.
This model is fitted with NBR (nitrile) seals as standard, suitable for general industrial air service within the standard -20 to +70 °C temperature band. It uses PT1/4 ports and includes an adjustable air cushion to decelerate the 20 mm rod smoothly at end-of-travel, protecting tooling during high-cycle operations.

Where the Airtac SC50 Standard Cylinder SC50X50N Is Used
Pneumatic Clamping
Short 50 mm stroke and 982 N force at 0.5 MPa make this cylinder ideal for workpiece clamping in machining and welding fixtures where rapid, repeatable holding force is needed.
Ejection & Stamping
Delivers a crisp 50 mm push for ejecting parts from dies or light stamping operations. The adjustable cushion reduces impact noise at the end of the stroke.
Diverting & Stopping
Used on conveyors as a pneumatic stop or diverter gate actuator. The NBR seals handle typical factory air, and the compact 200 mm extended length fits tight machine envelopes.
Is the Airtac SC50 Standard Cylinder SC50X50N the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa, while the 40 mm bore offers 628 N for lighter, faster cycling. The SC50X50N is a basic configuration without magnet or mounting accessories—order the -S variant if barrel-mounted position sensors are required. When replacing an existing cylinder, match bore, stroke, PT port thread, NBR seal material, and confirm the tie-rod body length A of 150 mm to ensure dimensional fit.
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 SC50X50N FAQ
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force increases to 1374 N. The maximum operating pressure is 1.0 MPa, yielding 1767 N of push force.
It can replace another tie-rod cylinder with matching 50 mm bore, 50 mm stroke, PT1/4 ports, and a body length of 150 mm. The SC series is not an ISO 15552 profile cylinder, so it is shorter than standard ISO units and will not drop into an ISO 15552 footprint without adapter plates.
