## Abstract

Metal cage for roller bearings, comprising two cage side parts, between which the rollers are held, wherein a plurality of holding elements which permanently connect the cage side parts to one another are arranged essentially parallel to the rotational axis of the rollers which are held between two holding elements, are not rotatably mounted on the cage side parts and are spaced apart from the holding elements.

## Claims

### Claim 1

A metal cage for roller bearings, comprising two cage side parts between which the rollers are held, a plurality of retaining elements fixedly connect the cage side parts to one another and are arranged substantially parallel to a rotary axis of the rollers which are held between two retaining elements and which are not rotatably mounted on the cage side parts and which are spaced apart by the retaining elements.

### Claim 2 (depends on 1)

The metal cage as claimed in claim 1, wherein the retaining elements are connected, as separate components, to the cage side parts.

### Claim 3 (depends on 2)

The metal cage as claimed in claim 2, wherein the retaining elements are retaining pins or retaining webs.

### Claim 4 (depends on 1)

The metal cage as claimed in claim 1, wherein the metal cage is a single-piece cast part.

### Claim 5 (depends on 4)

The metal cage as claimed in claim 4, wherein the retaining elements are round or polygonal in cross-section.

### Claim 6 (depends on 1)

The metal cage as claimed in claim 1, wherein sections for detachably fastening spacers, which are positioned between two of the rollers and which space the rollers apart from one another, are provided on the retaining elements.

### Claim 7 (depends on 6)

The metal cage as claimed in claim 6, wherein the sections are formed as cross-sectional constrictions or as plug-through recesses.

### Claim 8 (depends on 1)

The metal cage as claimed in claim 1, wherein, in an assembled position, retaining elements are arranged between two of the rollers, the retaining elements serve to support a spacer which is guided between the retaining elements and which is mounted on the retaining elements.

### Claim 9 (depends on 8)

The metal cage as claimed in claim 8, wherein an aperture for holding a fixing element, which serves to fix a spacer, is provided on each of the cage side parts, between the two retaining elements, which are positioned between the two rollers.

### Claim 10 (depends on 2)

The metal cage as claimed in claim 2, wherein a plurality of further retaining elements, which serve as axle pins for rollers with through bores, are provided.

### Claim 11 (depends on 10)

The metal cage as claimed in claim 10, wherein the further retaining elements are distributed symmetrically about the periphery of the cage.

### Claim 12 (depends on 1)

A roller bearing comprising two rings and at least one metal cage, which contains rollers, as claimed in claim 1.
