A roller shoe structure for high-accuracy straight-line guiding of construction units moving on other comprises a main body with component parts forming straight-line sections of a self-recurrent closed roller guiding raceway, raceway sections reversing the motion of the rollers, and a train of load bearing rolling element with recirculation motion, characterized in that side-guide clamping grooves (z1) and retaining insert clamping grooves (z2) are shaped in the main body (1) for engaging the main body (1) with side-guides (2), which ensure straight-line guiding of the rolling elements (5), and retaining inserts (3), which prevent the rolling elements from dropping out of the roller shoe structure if not built in, respectively, without using any binding element.
