## Abstract

A rolling bearing arrangement with at least one outer bearing ring and at least one inner bearing ring and with rolling bodies guided in raceways between the bearing rings. At least one damping body is provided for mechanical vibration damping. The damping body reduces the vibration transmission to at least one component following in the force flux. At least one damping body is materially bonded to at least one of the bearing rings.

## Claims

### Claim 1

A rolling bearing arrangement, comprising:
at least one outer bearing ring;
at least one inner bearing ring;
rolling bodies guided in raceways between the outer bearing ring and the inner bearing ring;
wherein at least one damping body is provided for mechanical vibration damping between the bearing and a component;
the at least one damping body being a foamed polymer or a metal foam, the at least one damping body materially bonded to at least one of the bearing rings, and the at least one damping body being designed as a fastening flange including a blind hole with a threaded insert, whereby the at least one damping body is connectable to the component via a fastener threaded into the threaded insert; and,
wherein the blind hole is contiguous with the at least one damping body.

### Claim 2 (depends on 1)

The rolling bearing arrangement of claim 1, wherein the damping body forms at least one substantially annular damping region of the at least one of the bearing rings and is materially bonded to the latter in an annularly encircling manner.

### Claim 3 (depends on 1)

The rolling bearing arrangement of claim 1, wherein the damping body forms the free ring region of the outer bearing ring.

### Claim 4

A method for producing a rolling bearing arrangement, comprising: at least one outer bearing ring; at least one inner bearing ring; and rolling bodies guided in raceways between the outer bearing ring and the inner bearing ring, wherein at least one damping body is provided for mechanical vibration, the method comprising:
foaming the at least one damping body and applying the foamed at least one damping body on at least one of the bearing rings, and
forming a blind hole in the at least one damping body and inserting a threaded insert into the blind hole, whereby the at least one damping body is connectable to a component;
wherein the blind hole is contiguous with the at least one damping body.

### Claim 5 (depends on 1)

The rolling bearing arrangement of claim 1, wherein the vibration-damping material is epoxy resin foam.

### Claim 6 (depends on 4)

The method of claim 4, wherein the at least one damping body is made from an epoxy resin foam.
