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.

In a wire race bearing, highly resilient bearing rings made of wire assume the function of the bearing arrangement. This saves weight and space. The free choice of material and the free design of the enclosing structure also allow the weight of the overall product to be reduced considerably.
In wire race bearings, the raceways of the rolling elements are precisely matched to the diameter of the rolling elements. This ensures optimum functional characteristics and guarantees both, precise running and a long operating life.
The races of Franke wire race bearings are made of hardened spring steel. Shocks and vibrations are absorbed by them. The result: a high resistance against such disturbing influences.
Slight deformations of the enclosing structures, for example due to temperature changes, are compensated by the flexible Franke bearing element. Where other roller bearings fail, the Franke bearing continues to roll.
Does your application focus on dynamics or precision? Or does a good compromise have to be found? The rotational resistance of a wire race bearing is adjustable. Suitable for each application. At any time.
Franke bearing elements can be used in a wide variety of designs. The demands on the enclosing construction are low, because it is not directly exposed to the loads. The main load is borne by the wire race bearing. This allows you to determine almost freely the ideal shape and material of your further construction.
You can purchase from Franke only the bearing elements or ready-to-install bearing assemblies. On request in customer-specific design, with toothing or with integrated torque motor.
