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.
