ABSTRACT:
A split roller bearing comprises a split inner race having a radially outwardly directed inner race surface, a split outer race surrounding the inner race and having an inwardly directed outer race surface generally concentric with the inner race surface, an annular row of rollers engaged radially between the inner and outer race surfaces, and a plurality of similar roller cage parts together forming an annular roller cage lying mainly between the inner and outer surfaces and formed with respective radially opening windows receiving the rollers. The cage parts each have a radius of curvature smaller than the radius of curvature of the inner surface in an unstressed condition. Thus it is possible to provide adequate material thickness at the ends of the cage parts to prevent the cage from wearing out at these locations. Since the rollers are movable radially in the pockets there is no binding between the rollers and the cage.
