Abstract
A bearing unit (10, 10′) has a radially outer ring (31). The outer ring (31) is rotatable with respect to an axis of rotation (X) and is provided with a radially inner raceway (31r). A stationary radially inner ring (33) is provided with a radially outer raceway (33r). A row (132) of rolling bodies (32) is interposed between the radially outer ring (31) and the radially inner ring (33). Each rolling body (32) has three contact points (P1, P2, P3) with the raceways (31r, 33r) of the radially outer ring (31) and, respectively, the radially inner ring (33).
