A bearing assembly includes first and second rolling-element bearings each having an inner ring with a running surface for rolling elements and a guide flange that extends radially outwardly beyond the running surface for limiting axial movement of the rolling elements. The inner rings are configured such that they are in contact with each other exclusively within a contact surface diameter that is smaller than an average value of a maximum diameter of the running surface of one of the inner rings and a maximum outer diameter of that inner ring. The guide flanges are disposed on sides of the inner ring of the first rolling-element bearing and of the second rolling-element bearing that face each other axially.

Bearing assembly

A bearing assembly includes first and second rolling-element bearings each having an inner ring that is connectable to a shaft for rotation therewith, each inner ring having a running surface (raceway) for rolling elements and an intermediate ring disposed axially between the inner ring of the first rolling-element bearing and the inner ring of the second rolling-element bearing. The intermediate ring has a maximum outer diameter smaller than a maximum diameter of the running surface of the inner ring of the first rolling-element bearing and smaller than a maximum diameter of the running surface of the inner ring of the second rolling-element bearing. The intermediate ring has an axial dimension that is smaller than a radial dimension of a cross-section of the intermediate ring, and that is smaller than 0.5 mm.
