Abstract
The invention relates to a method of manufacturing a roller bearing comprising a cage made from a thermoplastic polymer-containing material. By cross-linking the polymeric material its properties, such as form retention and compatibility with lubricants, are improved. A roller bearing provided with a cage made from suitably cross-linked thermoplastic polymer-containing material can be used even at temperatures above the melting point of the polymer. According to the invention a roller bearing is manufactured by forming a cage from thermoplastic polymer-containing material, providing it with rotating bodies and only then cross-linking the material. This avoids damage to an otherwise already rigid cage during the insertion of the rotating bodies.
