Abstract

A bearing unit () has a central axis (X) of rotation and a retaining cage () for a plurality of rolling bodies () interposed between a radially outer ring () and a radially inner ring (). The retaining cage () has a plurality of movable sectors () that are made of polymeric material, are identical to one another, and are arranged circumferentially adjacent to one another. Each movable sector () has at the ends a first engagement portion () and a second engagement portion () that are configured to define a dovetail joint between the first engagement portion () of a first movable sector (') and the second engagement portion () of a second movable sector (″), circumferentially adjacent to the first movable sector (′) to create a circumferential and radial constraint as well as a degree of axial freedom between the two movable sectors (″).
