The Franke-Principle of Bearings
Four wires for better design
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.

It couldn't be
easier or more compact
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.
Runs precisely.
And runs precisely.
And runs precisely.
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.
Shock and impact elastic
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.
Compensates deformations
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.
No bearing play. Adjustable rotational resistance.
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.
Possibilities
instead of
specifications
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.
Bearing Elements
All you need for your product solution with wire race bearings is a Franke bearing element. Franke bearing elements can be integrated directly into your design. You can easily assemble them yourself. The bearing element can be adapted in form and material bespoke to your requirements, for example by choosing amagnetic ceramic rolling elements.
Bearing Assemblies
If required, we can also design and manufacture complete bearing assemblies for you. These can be mounted even more easily than bearing elements. Franke bearing assemblies are available in every size, with individual bores and toothings and in numerous materials such as aluminium, stainless steel, carbon or as a 3D printed housing.
Rotary Tables/Systems
You prefer a complete solution from one source? Franke offers complete customized positioning and drive units, optionally with proximity switch, coupling and motor. Systems with direct drive are a particular strength of Franke. They are used, for example, in many computer tomographs of renowned manufacturers.
