About the Airtac SC50 Standard Cylinder SC50X225
The SC50X225 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, 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. With a 50 mm bore and a 225 mm stroke, this model uses a 20 mm diameter piston rod with M16x1.5 threads and features an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.
This cylinder has a body length A of 150 mm, resulting in a total extended length of approximately 375 mm. It operates on filtered air (40 µm) within a standard pressure range of 0.15–1.0 MPa and a temperature range of -20 to +70 °C using its default TPU seals. The SC50X225 is a genuine AirTAC component, built for reliable linear actuation in industrial automation.

Where the Airtac SC50 Standard Cylinder SC50X225 Is Used
Material Transfer Gates
Provides the 982 N push force at 0.5 MPa needed to actuate diverter gates on conveyor lines, reliably sorting packages with a 225 mm stroke.
Clamping & Fixturing
Delivers a controlled 1767 N clamping force at 0.9 MPa for holding workpieces during welding or assembly, with a 21 mm cushion for quiet operation.
Press-Fit Assembly
Ideal for light press operations, using its 20 mm rod and 225 mm stroke to insert bearings or bushings with consistent, repeatable force.
Is the Airtac SC50 Standard Cylinder SC50X225 the Right Cylinder?
Select the SC50X225 when your application requires a force between the 628 N of the SC40 series and the 1559 N of the SC63 series at 0.5 MPa. For strokes of 225 mm, the rod's bending moment capacity should be checked if side loads are present; consider an external guide or a guided cylinder for non-axial forces. To ensure a correct replacement, match five key aspects: the 50 mm bore, the 225 mm stroke, the PT1/4 port thread, the basic (no bracket) mounting, and the absence of a built-in magnet.
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 SC50X225 FAQ
At 0.5 MPa, the cylinder provides a theoretical push force of 982 N and a pull force of 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than a standard ISO 15552 cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 cylinder with a 225 mm stroke, PT ports, basic mounting, and no magnet.
