Claims

[Claims for Utility Model Registration] (1) A guide rail that extends in the axial direction and has an axial track surface on its outer surface, and a guide rail that straddles the guide rail so as to be movable in the axial direction along the track surface. A linear roller guide device comprising a suspended slider, and a roller circulation bearing having a row of rollers that endlessly circulates and rolls on the raceway surface is attached to the side of the slider facing the guide rail, The guide rail has a generally T-shaped cross section, the upper surface of which is the raceway surface of a roller circulation bearing that receives a load from above to the bottom, and the side surface of the lateral projecting portion of the guide rail that receives a lateral load. The lower surface of the lateral overhanging portion of the guide rail is the raceway surface of the roller circulation bearing that receives the load from below upwards, and the slider has rollers at positions facing each of the above raceway surfaces. A linear roller guide device equipped with a circulation bearing. (2) A roller circulation bearing that is in contact with the raceway surface on one of both sides of the lateral overhanging portion of the approximately T-shaped guide rail, and a roller circulation bearing that is in contact with the raceway surface on the lower surface of the overhanging portion. 2. The linear roller guide device according to claim 1, wherein the bearing is provided with preloading means for preloading the roller against the raceway surface. (3) A claim characterized in that the preload means includes a disc spring, and at least one preload means is provided with a preload adjustment bolt for releasing the preload load.
(2) The linear roller guide device described.
