CDUK20-20D SMC Double-Acting Non-Rotating Free Mount Cylinder

The SMC CDUK20-20Dis a premium, high-precision industrial free-mount pneumatic air cylinder belonging to the versatile CU Series.Engineered to deliver precise linear force within highly confined machine layouts, this compact actuator features a specialized non-rotating rectangular piston rod mechanismthat prevents rotational deflection under load without requiring external guiding lines. Operating on a double-acting action profile, it utilizes compressed air to reliably power both extension and retraction strokes.

As prominently displayed through the clear retail film packaging in image_26be60.jpg, the cylinder features a streamlined block-shaped housing with multi-surface pre-drilled through-holes, giving installation engineers the complete freedom to mount the unit directly to machine walls from any face without using space-consuming external brackets. The laser-etched face clearly details its factory model code, Made in Japan manufacturing origin, integrated tracking code, and an optimized operational pressure limit ranging from 0.15 to 0.7 MPa. Additionally, the body includes built-in magnetic piston components and dedicated recessed channels along its flanks to support flush-mounted auto-switch positio
