Claim Text:
1. A cage for separating rollers in a toroidal roller bearing having an outer ring and an inner ring, the toroidal roller bearing allowing for axial and angular displacement between the outer and inner ring, the cage comprising, a first and second annular ring displaced axially from each other and forming first and second axial ends of the cage, respectively, a plurality of elongated axial members interposed between the first and second annular rings and thereby forming a number of roller pockets, each roller pocket meant to receive at least one roller element, the first annular ring comprising a portion extending radially inwardly from the elongated axial members and forming at least a part of the first axial end of the cage, the portion is at least partly located at a radius being smaller than a minimum radial location of the elongated axial members and wherein a minimum radius of the first axial end is a smallest radius of the cage, the portion further extending in at least a part of the circumference of the first annular ring and having a bottom surface configured to contact the inner ring during operation, wherein a radially outer peripheral surface of the first annular ring presents axial grooves at least at the circumference having the portion, each of the axial grooves is located at an axial end face of each roller pocket and has a groove radius that is less than the minimum radial location of the elongated axial members, the axial grooves extend axially to the first axial end of the cage and are at least partially radially aligned with the portion such that a roller can be inserted and pulled out via the axial groove into and out of each roller pocket while the cage is at least partially radially between the inner and outer rings, and wherein the portion is at least partly located at the radius being smaller than a minimum groove radius.
