Patent ID: 8622622

Claim:
An antifriction bearing for a turbocharger, comprising: an outer ring with an annular inner face; an inner ring with an outer face which is parallel to the inner face; and a rolling body cage comprising a single annular part which is arranged radially between the outer ring and the inner ring with, in each case, one cage guiding face which is parallel to the inner face of the outer ring and an inner surface which is parallel to the outer face of the inner ring, and with closed rolling body pockets which are distributed over a circumference and rolling bodies which are received in the rolling body pockets, wherein a plane drawn through center points of the rolling bodies and running perpendicularly with respect to a rotational axis of the antifriction bearing divides the annular part into two axial annular sections, one of the two axial annular sections being an axially broader annular section having an axial width that is greater than an axial width of the other of the two axial annular sections, the cage guiding face being provided on the axially broader annular section and the cage guiding face having at least one radial recess outside the rolling body pockets and the axially broader annular section being damped hydraulically with respect to the outer ring by means of the at least one recess.
