Abstract: The invention relates to a compact linear roller guide which makes it possible to transmit high forces and torques between a carriage (1) and a guide rail (3). The carriage (1) comprises two or more pairs of ribbed rollers (2), rotatably supported on the side walls of the carriage by means of bearings, between which the rail (3) is inserted, with a complementary cross-section, The simultaneous contact of the planar and convex surfaces of the rail (3) with the cylindrical and concave surfaces of the rollers (2) enables uniform distribution of the loads on said bearings and a compact configuration of the guide.
