Abstract: A full-complement anti-friction bearing is disclosed which includes a plurality of rolling elements, an inner bearing body in the form of a shaft or an axle with a cylindrical outer diameter, and an outer bearing body arranged concentrically with the latter and having an inner bore. In an exemplary embodiment, all rolling elements have the same outer diameter and are arranged between the inner bearing body and the outer bearing body in such a way that the rolling elements roll on the outer diameter of the inner bearing body and on the inner bore of the outer bearing body, the outer bearing body being thus rotatably supported relative to the inner bearing body. In addition, the full-complement anti-friction bearing is configured without a cage.

Abstract: The present invention relates to a screw assembly with a threaded spindle and a spindle nut. The spindle nut comprises at least one threaded portion made of sintered material with an internal thread. The internal thread engages in an external thread of the threaded spindle. It is according to the invention provided that the internal thread and the external thread are configured as steep threads.

Abstract: The invention relates to a backlash-free planetary gear unit with a sun gear and with a ring gear, which mesh with at least one first planet gear of a planetary stage, wherein the planetary stage comprises a first planet carrier on which the first planet gear is rotatably mounted, wherein there is furthermore at least one second planet gear in the planetary stage that also meshes with the ring gear and the sun gear, wherein the at least one second planet gear is rotatably supported at a second planet carrier of the planetary stage, wherein the two planet carriers are in the circumferential direction of the sun gear preloaded relative to each another such that also the at least one first planet gear is preloaded relative to the at least one second planet gear in the circumferential direction of the sun gear.
