ABSTRACT:
A linear motion rolling contact guide unit assembly includes a U-shaped guide rail which extends straight over a desired length and which is formed with a pair of guide grooves. The assembly also includes a slider unit which is mounted in the guide rail so as to be movable relative to the guide rail along a longitudinal axis of the rail. The slider unit is formed with a pair of endless circulation paths each of which includes a load path section, a return path section and a pair of connecting path sections which connect the corresponding ends of the load and return path sections. A plurality of rolling members are provided in each of the endless circulation paths. A window is formed in the side of the slider unit at the load path section and the rolling members are partly exposed at the load path section and partly received in the corresponding guide groove of the guide rail. The slider unit includes a top plate formed with at least a part of an upper half of each of the endless circulation paths and a split bottom plate formed with the rest of the endless circulation paths.
