Abstract

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.
