Franke Rotary Bearings

Frustrated with trying to fit conventional bearings into your application? Franke rotary bearings offer maximum design freedom, without compromising precision or load capacity. Mating structures can be designed in a variety of lightweight materials and perfectly adapted in its geometry to ensure they are bespoke to your application. Franke Rotary Bearings offer substantial design freedom and free selection of material. With minimal mounting space for bearing elements, slim bearings, bearing assemblies, motorised rotary tables, and integrated direct drives, allows for innovative design

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.

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.

Bearing Assemblies

Franke Bearing Assemblies come ready to install in a large selection range. Preloaded free from clearance and optimised for rigidity, speed and service life. Infinitely variable from 100 to 1800 mm with selected diameters available ex works.

Slim Berings

Franke slim bearings deliver a convincingly smooth run, require an extremely compact mounting space and are simple to assemble. Slim bearings consist of one inner and one outer race ring with hardened and profiled raceways and a plastic cage with retained balls. The rolling elements touch the race rings at two points each, hence ensuring the 4-point system. The race rings are separated; their diameter can therefore be altered elastically for mounting.

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.
