ABSTRACT:
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).
