Abstract
A ball bearing wherein each holder has only one oval-shaped race and a plate-like bearing surface member formed as a gutter-like circulating bearing surface conforming to the oval shape with four ball holders situated in the housing such that the bearing surface members run obliquely outward toward one another so that the straight race sections for the balls absorbing the load at one edge and the other straight race sections at the other edge run essentially along the ribs of two rectangular parallelpipeds having different cross-sectional dimensions.
