Tunnel drive shaft,tunnel cardan shaft,Through cross shaft universal couplings
Different to our SWP cardan shaft and SWC Universal Coupling,the tunnel shaft also called through cross shaft universal couplings, with tight structure and stable transmission, are used in middle and small rolling mill.
Also it is good choice for daniel style mills,vertical applications,and other applications which involves long length compensation in limited length space.
There are 2 types of the tunnel shafts,SWC-ZG perforation type front mounting tunnel shaft and SWC-FG perforation type behind mounting tunnel shaft.
The designs and technical data of journal cross assemblies vary with different types of universal joint shafts. The most commonly used are the cross assemblies for SWC-ⅠSeries and SWC Series Universal joint shafts,
