Ball bearing spring ribbon

Borrelly Anneau élastique

Designed to preload bearings

Borrelly ribbon springs are a continuous wave formed sheet manufactured from spring material. They are mounted between bearing and housing; their role is to permanently control the play between those both elements.

On assembly, the ribbon spring is preloaded, and bearing only moves in radial direction if global preloading force is exceeded.

Borrelly ribbon springs are available in both carbon and stainless steel.
