Franke Wire Race Ball Bearings
In 1934 Mr E Franke invented the wire race ball bearing. With this system the rolling elements are not in direct contact with the enclosing bearing ring. They run on spring-hard wire rings which are provided with ground races. The specific advantages of this bearing type are e.g. space saving, inner flexibility, high load capacity, robustness and free selection of materials.
During the seventies the principles of the bearing system were applied to the sector of linear guides. In the meantime both structural elements, the Franke antifriction bearing as well as the Franke linear guide, have prevailed among experts.
