3D Printed Bearings

Lightweight bearings from a printer? traditional bearings take metal & reduce the content to produce inner & outer rings. Franke 3D print bearings reverse this process & use an additive concept by using laser sintered aluminium particles to create the housings enabling super lightweight internal honeycomb housings to be produced.

Prototypes already produced are under test to compare performance with traditional designs. See news of latest developments.

An ingeniously simple principle

Our Wire Race Bearings are based on a simple yet ingenious principle: Individual race rings made of wire are fitted with a raceway that is designed precisely to match the diameter of the rolling elements. Therefore, the rolling action does not take place directly between the rolling elements and mating structure, but rather with low-friction on the four open race rings. This engineering principle permits free design of the mating structure in terms of its geometry and material selection.

Compact and lightweight

Wire Race Bearings are extraordinarily compact and fit snug in even the tiniest mounting spaces. They are available either as bearing elements (consisting of race rings, rolling element and cage), or as ready-to-use bearing assemblies together with the mating structure. Their compact form and the free material selection for mating structures permit the construction of lightweight designs whose low masses also require less operating power.
