ST Cardan Shaft
Long Flanged Rigid Shaft – Type D Series
The Heavy & Medium Duty Type D Series is designed with an extended flanged rigid structure, making it the ideal solution for equipment requiring greater shaft lengths. It is widely used in rolling mills, conveyo r systems, and large-scale industrial machinery, where longer shaft spans are necessary for stable and efficient power transfer.
This series offers multiple models with the following specifications:
● Nominal torque: 21–1,250 kN·m
● Flanged diameter: 160–620 mm
● Length range: 520–1,720 mm (custom lengths available)
Below are the technical drawings and detailed product parameters for the Type D Series.
