Ball Bushing Guide
A ball bushing guide is a so-called round or shaft guidance in which a linear guide is realized via usually two parallel shafts as a guide element and in which linear ball bearings, so-called linear ball bushings, are used as guide sleeves instead of plain bushings.
A ball bushing guide is usually the simplest and most favorable type of linear guide with rolling bearings and is characterized by smooth running and low clearance.
