ST Cardan Shaft
Flanged Rigid Shaft - Type C Series
The Light Duty Type C Series adopts a flanged rigid connection, designed for applications that require precise alignment and steady torque delivery. It is widely used in light industrial transmission systems, printing machines, and packaging lines where compact installation and consistent performance are essential.
This series includes 10 models with the following specifications:
● Nominal torque: 150–22000 N·m
● Flanged diameter: 58–225 mm
● Standard length: 128–400 mm (custom lengths available)
Below you can find the design drawings and detailed product parameters for the Type C Series.
