The Franke-Principle

Four wires for better design

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.


Anything you wish.
Only what you need.

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.
