Recirculating ball track telescope interface assembly for steering column

An axially adjustable steering column assembly comprising:

• a first support structure;
• a second support structure, wherein the first support structure is axially adjustable relative to the second support structure in a telescoping manner;
• and
• a plurality of telescope interface assemblies disposed between the first support structure and the second support structure, each of the telescope interface assemblies comprising:
• a track formed in at least one of the first support structure and the second support structure;
• and
• a plurality of metal balls disposed in the track to provide a rolling interface between the first support structure and the second support structure during axial adjustment therebetween, wherein the first support structure, the second support structure and the plurality of metal balls are each formed of steel, wherein each of the plurality of balls is in contact with the first support structure and the second support structure while in a first portion of the track, and wherein each of the plurality of balls is in clearance with one of the first support structure and the second support structure while in a second portion of the track.
