Abstract

A roller bearing which has a roller bearing ring. In order to produce a roller bearing that has a high rotational speed value and operational load using minimum quantity lubrication and in which heat produced in the bearing can be removed in a rapid and reliable manner, the roller bearing ring is made of a material composite. The first material composite component forms the running surface and is made of a refractory metal or a sintering material. The thermal conductivity and heat resistance first material composite component is higher than the thermal conductivity and heat resistance of at least one additional material composite component which forms the base body of the roller bearing ring.
