| 摘要 |
The invention relates to rolling bearings and concerns particularly the design of retainer and possibly guiding ring of such bearings. The invention is characterized thereby that the retainer or the guiding ring incorporates rings (3) of the material having the same coefficient of thermal expansion as the material of the race rings. These rings are embedded e.g. in plastic, which has another coefficient of thermal expansion than that of the material in the rings.
