Abstract
A window cage for a cylindrical roller bearing includes a U-shaped cross section, annular cage having opposite cage rings which engage the ends of the rollers and webs joining the cage rings and extending between the rollers. The opposite sides of each web converge in the radial direction inwardly of the pocket recesses for the rollers. Therefore, spaced apart, opposing sides of two adjacent webs converge in the radial direction outwardly of the pocket recesses to engage a roller in the recess from behind. Radially outward beyond the converging surfaces, the web sides have generally parallel surfaces which are spaced apart slightly less than the diameter of the roller. Recesses are defined in the cage rings at the bottoms of the pocket recesses.
