ST Cardan Shaft
Short Flanged Rigid Shaft – Type C Series
The Heavy & Medium Duty Type C Series is engineered with a flanged rigid structure in a short, space-saving format. It is ideal for heavy-duty equipment such as straightening machines, mixers, and crane drives, where compact installation and strong torque delivery are essential.
This series offers multiple models with the following specifications:
● Nominal torque: 21–1,250 kN·m
● Flanged diameter: 160–620 mm
● Length range: 380–1,360 mm (custom lengths available)
Below are the technical drawings and detailed product parameters for the Type C Series.
