Abstract
One of two races of a roller bearing is equipped with a sliding ring exteng thereabout, with a melting ring formed of material having a melting point higher than the normal operating temperature of the bearing being interposed between the one race and the sliding ring. Malfunction of the bearing such as might occur by seizure of the bearing rollers will cause at least partial melting of the melting ring whereupon the one race is placed in relative sliding engagement through the melting ring with the sliding ring.

In a roller bearing assembly including a first race, a second race and bearing rollers operatively interposed therebetween, the improvement comprising a sliding ring arranged about one of said races and a melting ring interposed between said sliding ring and said one race, said melting ring being composed of material having a melting point higher than the normal operating temperature of said bearing, the material of said melting ring being such that it will melt when the operating temperature of the bearing rises above a normal operating temperature, with at least partial melting of said melting ring operating to enable relative sliding motion between said one race and said sliding ring.
