Abstract: A part registration system for registering one or more parts relative to a robot having a robotic arm that defines a plane of optimal reach at a vertical position is provided. The part registration system includes a tray support rack, a tray support shelf and a tray transfer arrangement. The tray support rack is configured to support a plurality of trays for holding one or more parts. The tray support rack has a plurality of tray support regions in which one or more trays may be supported. The plurality of tray support regions are at different vertical positions. The tray support shelf is vertically adjustable relative to the tray support rack. The tray transfer arrangement transfers the trays between the tray support rack and the tray support shelf. Methods are also provided.

Abstract: A multiliner for a ball nut, a ball nut and a ball screw assembly are provided. Methods of forming the multiliner are also provided. The multiliner includes return channels that are configured to prevent bearing balls from falling out of a retaining region in a radial direction. This allows bearing balls to travel past intermediate grooves formed in a cooperating threaded ball screw shaft.

Abstract: A motor is provided. The motor includes a motor body and a rotor assembly. The rotor assembly includes a magnetic core mounted to a rotor shaft. The rotor assembly may include standoffs for accurately axially locating the magnetic core relative to rotor bearings. A drive nut adjustment arrangement may be provided. A mechanical interconnection between the drive nut and rotor shaft may be provided. A trailing end lead screw support may be provided. An axial preload arrangement may be provided to axially locate the rotor assembly within the motor body.
