This Double Joint is used for the same application as series 0.400, namely in steering axles of all wheel drive vehicles. However, the design of series 0.500 differs slightly from that of series 0.400.
The joint pivots are not located in one plane thus enabling a more compact design. This feature shortens the distance between the centerpiece which results in a shorter installation length.
Series 0.500 offers more joint sizes than series 0.400 thus covering a wider torque range.
