Abstract
A cage for a radial bearing assembly with rolling elements is provided. The cage includes a first and second rims, and webs extend between the rims to define pockets that receive rolling elements. Each of the webs includes first and second rolling element guide surfaces that face a first adjacent one of the pockets and third and fourth guide surfaces that face a second adjacent one of the pockets. These guide surfaces are located at a pitch circle adapted to coincide with a centerline of the rolling elements located in the pockets. The webs have first and second radially inner retention tabs that respectively face the first and second adjacent ones of the pockets. The first retention tab is located axially between the first and second guide surfaces and the second retention tab is located axially between the third and fourth guide surfaces. The retention tabs are located radially inside the pitch circle.
