The rollers running directly between the shaft and housing secure an appreciable saving in bearing size and weight. With the elimination of races the assembly is so simple that the roller cage slides between the shaft and housing easily, and runs firmly and freely. This phenomenon is achieved by the precision in the manufacture of Roller and their disposition in the cage.
