ABSTRACT:
The disclosure concerns a ball bushing which is adapted for unlimited longitudinal movement on a shaft. The ball bushing includes a sleeve having a plurality of longitudinally extending ball channels defined in it. Each ball channel has two longitudinally extending sections which are joined by two curved sections at the end of the longitudinal sections. A needle is positioned in and extends the length of each channel and the longitudinal sections of the ball channel are shaped and positioned so that the needle contacts and guides and prevents falling out of the balls in each longitudinal section. The curved sections of the ball channel wrap part way around the needle.
