Abstract

A method for producing a cage of a rolling bearing, for receiving a rolling body. The body of the cage is a plastic material that can be cross-linked by radiation, and is provided with rolling bodies later during the method. The body of the cage is fitted with the rolling bodies only once the structure of the cage has been exposed to the radiation. Also, a cage is disclosed for receiving rolling bodies of a rolling bearing, which has a body consisting of a plastic material.

Claims (15)

1 - 7 . (canceled)

8 . A method for producing a cage, which has a body, of a rolling bearing that receives rolling bodies, the method comprising the following steps:

producing the body of the cage from a cross-linkable thermoplastic plastic material;

exposing the body to radiation; and

fitting the body of the cage with the rolling bodies after the body is exposed to radiation.

9 . The method as claimed in claim 8 , further comprising a thermal treatment of the body of the cage before the fitting of the cage with the rolling bodies.

10 . The method as claimed in claim 9 , the thermal treatment is carried out after the cage us exposed to the radiation.

11 . The method as claimed in claim 8 , wherein the radiation is high-energy electromagnetic radiation.

12 . The method as claimed in claim 11 , wherein the high-energy electromagnetic radiation is x-radiation.

13 . The method as claimed in claim 8 , wherein the radiation is particle radiation.

14 . The method as claimed in claim 8 , wherein the producing step includes producing the body of the cage to include pigments which change color when exposed to the radiation.

15 . A cage of a rolling bearing which receives rolling bodies, comprising:

a body which is produced from a plastic material that can be cross-linked by exposure to radiation and which is fitted with the rolling bodies.

16 . A cage for receiving rolling bodies of a rolling bearing, comprising:

a body made of a plastic material containing pigments which change color under an influence of radiation and/or heat.
