Aluminum, 3D-printing and Carbon CFRP for up to 90% weight reduction Used in thousands of applications: Franke Wire Race Bearings and Linear Systems The weight savings of 3D-printed bearing assemblies compared to a conventional steel bearing can be as much as 90%. If the use of different materials for the enclosing design with comparable bearing diameters already results in significant savings, the result is further improved by the use of 3D printed housing rings. Due to their characteristics and properties, Franke wire race bearings are predestined for lightweight design. Reduced to the essentials, they enable completely new designs of the bearings and the use of light materials for the housing parts. On the basis of state-of-the-art production technologies, light-weight bearings are created with substantial weight, energy and space savings with comparable stiffness and highest precision over the entire service life. Lightweight wire race bearings comparable bearing assembly made of Wire Race Bearings for Lightweight Design different materials and production processes.

The most important component of these enclosing constructions are the extremely light and compact wire race bearings from Franke. These have the effect that the housing parts are not directly exposed to the loads on the rolling elements and therefore can be designed particularly thin. Due to the possibility of the free design of the enclosing construction, the weight can be reduced, which means that additional components are often eliminated and entir
