Franke Direct drive bearing systems utilise the unique advantage of the Franke wire race bearing principle. By eliminating the inner & outer ring found in traditional bearing designs the wire race bearing element can be incorporated directly into the housing structure allowing you to use your choice of material, Aluminium, Carbon, Plastics, etc. In direct drive bearings the static part carries the stator whilst the rotating part works as the rotor of the electric drive.
Using Aluminium the complete direct drive bearing assembly is still lighter than an equivalent steel bearing. Higher dynamics & speeds are achieved with improved acoustics, & the concept is already well established & proven in the Franke “Flusterlager” bearings widely used in MRI & CT scanners throughout the world. Applications in filling, Dosing, PCB assembly & future use in electric vehicles is already well developed. Link to Franke
