Abstract
A linear motion guide for mounting and longitudinally guiding machine parts, in which a first guide element provided to be fixed to a machine part is guided by a plurality of rolling elements along a longitudinal movement axis with respect to a second guide element, likewise provided to be fixed to a machine part, for this purpose each guide element has a groove-like recess running parallel to the longitudinal movement axis, boundary surfaces of the recess in each guide element are provided as rolling surfaces for the rolling elements, the rolling elements are arranged one after another in one or more rows in at least one cage between the two guide elements, the cage is provided with at least one first positive guide, the cage with its first positive guide being guided by second positive guide fixed to the guide elements, each second positive guide being arranged only on one of the guide elements and being fixed in position relative to the latter. In order to provide this type of linear motion guide with accurate guidance and favourable fabrication and assembly properties, it is proposed that the second positive guide is fixed to the respective guide element (1, 2) outside the groo…
