ABSTRACT:
A linear guide/feed module has a tubular boom movable along a movement axis, a housing encompassing the tubular boom so that the boom is travelable out of and into the housing along the movement axis, a drive unit for driving the boom to move in relation to the housing, at least two recirculating rolling element rows supporting the boom in the housing for its movement in relation to the housing along the movement axis and spaced apart from each other in a circumference direction around the movement axis, with each of the recirculating rolling element rows having a force-loaded rolling element carrying segment extending essentially in a direction of the movement axis and an essentially unloaded rolling element return segment, and a guide body encompassing the boom at least in segments in the circumferential direction, provided in the housing and having rolling element passages of the rolling element return segments formed into it as well as raceways on a housing side of the rolling element carrying segments of the at least two rolling element rows.
