Abstract

A linear servo drive comprises substantially a drive section (29) and a ciage (30) running on the latter. The carriage (30) is seated on the drive section (29) via a roller bearing consisting of guide strips (36) extending in the axial direction and coacting with rollers (37, 37a to 37c). In order to increase the mechanical loading capacity of the drive section and, thus, of the entire drive and to reduce at the same time its weight, the drive section (29) is given a radial cross-section exhibiting flange-like end portions (34) extending in a star-like pattern from a central area (32) and provided with surface portions which extend in an approximately radial direction and which define the plane of the roller bearing.
