Franke lightweight aluminium LVB series rotary bearings are produced in sizes 100 – 1800, with bores from 50mm to 1670mm. Sizes 200, 300, & 400, are normally available from stock. The bearings are around 65% lighter than steel LVA equivalents & are fully assembled & ready to mount with pre-drilled/counterbored mountings on both inner & outer rings.
Other versions are available in steel, & options with internal or external gearings & external positive belt drives are available. A stock range in sizes 100, 200, 300, 400, 500, & 600, is offered on short delivery times.
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.
