Abstract: A thrust bearing characterized by simplicity of construction and improved life and including a pair of bearing races with a cage and rolling elements positioned between the races. Arcuately spaced lugs integrally formed on one bearing race extend in an axial direction and are provided with latching members thereon to engage the other bearing race and thereby hold the bearing races and the cage in assembled relation. An improved one-piece cage is disclosed having portions on each face of the cage which protrude outwardly for centering the cage between the opposing bearing races to facilitate proper guidance of the rolling elements.
