ST Cardan Shaft
Welded Rigid Shaft - Type B Series
The Light Duty Type B Series is built with a welded rigid design, offering stable power transmission without length compensation. It is well-suited for light industrial transmission lines, conveyor systems, and food processing machinery where consistent shaft alignment is required.
This series includes 10 models with the following specifications:
● Nominal torque: 150–22000 N·m
● Flanged diameter: 58–225 mm
● Standard length: 150–600 mm (custom lengths available)
Below you can find the design drawings and detailed product parameters for the Type B Series.
