Abstract

A bearing assembly comprising a roller mechanism and a cage member. The roller mechanism includes a plurality of roller members and a plurality of frangible connector links for initially connecting each roller member to an adjacent roller member. The roller members and the connector links are integrally molded together. The cage member includes a circular flange and a plurality of spacer pegs extending perpendicular from the flange in a circular configuration. The pegs are spaced apart from one another and each peg includes a tip having a hollow chamber adapted to receive and store a connector link. The pegs are adapted to be inserted between adjacent roller members during assembly such that when the cage member and the roller mechanism are pressed together, the pegs will sever the connector links from the roller members and will retain the severed connector links in the chambers of the peg tips. The severed roller members are then free to independently rotate within the cage member.
