Abstract: Having as a principal objective the increasing value of the limited speed of the existing four point contact ball bearings, but without a significant change to their known technology, the authors of this paper have began and developed researches concerning the new concept: planetary ball bearings. We illustrate this concept by homogenous planetary four point contact ball bearings. It offers and describes the theoretic obtaining solutions of homogenous planetary four point contact ball bearings by adequate assembling of known and currently used four point contact ball bearings, as well as specific constructive solutions of homogenous planetary four point contact ball bearings. The paper is further supported by a couple of 3D models of homogenous planetary four point contact ball bearings, and also by some of their possible performances.
