Abstract: This disclosure relates to a segmented retainer for rollers of a roller bearing. The retainer includes a pair of end rings having circumferentially spaced separator bars extending therebetween. The separator bars are fixedly secured to the end rings against displacement and rotation. Each separator bar has a configuration wherein at each side thereof there are two radially spaced bearing surfaces separated by a lubricant pocket. The convex shape of the bearing surfaces, in conjunction with the convex rolling surfaces of associated rollers provide for suitable lubricant pockets and lubricant flow thereby providing adequate lubrication between the roller and the separator bars. The bars are secured to the end rings by a plurality of different means including welding and interfitting mechanical interlocks.
