About the Airtac SC50 Standard Cylinder SC50X430
The SC50X430 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 430 mm stroke. At 0.7 MPa it generates 1374 N of push force, making it a capable mid-range actuator for linear transfer and pressing tasks. The 20 mm diameter piston rod and 21 mm adjustable air cushion help manage end-of-stroke deceleration effectively.
This 430 mm stroke model uses a PT1/4 port and an M16x1.5 rod thread, with a body length A of 150 mm. It operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C with its standard TPU seals. The SC design is a genuine AirTAC tie-rod cylinder, shorter than an ISO 15552 profile and built for reliable industrial service.

Where the Airtac SC50 Standard Cylinder SC50X430 Is Used
Part Transfer
Moves components between conveyor lanes or workstations with a 430 mm reach, using 1374 N of push force at 0.7 MPa for reliable shuttling.
Clamping & Fixturing
Applies consistent 1767 N clamping force at 0.9 MPa to hold workpieces during welding, assembly, or machining operations.
Material Pusher
Pushes cartons or products onto a packaging line infeed, leveraging the adjustable cushion to soften impact at the end of the 430 mm stroke.
Is the Airtac SC50 Standard Cylinder SC50X430 the Right Cylinder?
For applications needing slightly more force, stepping up to the 63 mm bore SC63 series provides 2182 N of push at 0.7 MPa. If space or weight is a concern, the 40 mm bore SC40 offers 879 N at the same pressure. Always match replacement cylinders across five key points: 50 mm bore, 430 mm stroke, PT port thread, basic (no bracket) mounting, and the absence of a magnet.
At a 430 mm stroke, the 20 mm rod is extended significantly. Avoid direct side loading, which can bend the rod or damage the bearing. For offset loads, use an external linear guide or consider a guided cylinder to protect the rod and seals from premature wear.
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 SC50X430 FAQ
At 0.7 MPa operating pressure, the SC50X430 produces 1374 N of push force and 825 N of pull force on the retract stroke.
No, the SC50X430 is a double-acting cylinder and will not hold position if pressure is exhausted or the valve is centered. The adjustable air cushion only decelerates the piston at stroke end; it is not a locking device. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
