Rotative Movement Principle Solutions Franke

The decisive difference between an ordinary ball bearing and a Franke wire race bearing is in the raceways. In a wire race bearing, the rolling elements do not roll on solid housing rings, but on high performance wires. The flexibility of this principle makes it possible to design more freely and simply, in order to develop better products.
