摘要： A bearing arrangement for guiding a carriage in a straight line along a guide rail has four endless courses of balls disposed between the guide rail and the carriage, and the guide rail is provided with four parallel ball races associated with the load-bearing balls of the ball courses. The balls are held in elongated ball bearing assemblies. The ball races are located in the respective transitional zones between two adjacent shanks, located one above the other, of the substantially double-T-shaped or cruciform guide rail.In order to increase the flexural strength of the guide rail and to provide a manner of securing it in a tilt-free manner, the arrangment is selected such that on at least one side the guide rail has two integral, longitudinal parallel ribs, which define a longitudinal groove in which securing devices for the guide rail and/or for elements insertable into the longitudinal groove are disposed, fitting seats between the ball bearing assemblies and the carriage insure accurate guidance.

摘要： A linear bearing arrangement for guiding a carriage in a straight line along a guide rail is provided with at least one endless course of balls (3) disposed between the carriage (2) and the guide rail (1). The guide rail has at least one ball race (4) associated with the load-bearing balls of the ball course and extending in the longitudinal direction of the rail. At least one elongated track carrier element (8), having at least one ball race (16), as well as at least one diversion and return track for the unloaded balls are disposed in the interior of the carriage.In order to assure great accuracy in the guidance of the carriage on the guide rail as well as to assure simple assembly and convenient replacement of worn parts, the arrangement is selected such that the track carrier element (8) is combined into one subassembly with diversion (9) and return elements (10,10a,11,11a) containing the diversion and return track; a plate (12) holds the balls (3) facing the rail (11) captive. The subassembly is fitted into the carriage (2) by engaging, fitting surfaces (15,18) and retained by end plates (33).
