Abstract
A telescopic column for a height-adjustable table comprises a cylindrical outer column, a cylindrical inner column at least partially arranged within the outer column, several balls, and a tube-shaped ball cage retaining the balls at positions relatively determined with respect to one another. The outer column comprises, along its longitudinal direction on its inside, an outer column running surface section configured such that the balls roll over thereon, the inner column comprises, along its longitudinal direction on its outer cross-section, an inner column running surface section configured such that the balls roll over thereon, and the inner column and the outer column are configured such that the balls, during an adjustment of a length of the telescopic column, roll over in an almost backlash-free manner on the outer column running surface section and the inner column running surface section in a predefined range of motion of the balls in order to guide the inner column in the outer column.
