ABSTRACT:
The rolling guide unit has a track rail formed with raceway surfaces, a casing moveable relative to the track rail and having raceway surfaces at positions facing the raceway surfaces of the track rail, and a number of cylindrical rolls that run rolling between the facing raceway surfaces. An end portion of that raceway surface of the track rail which is heavily loaded with a distributed load is crowned to make the raceway surface at the end portion curved, thereby eliminating uneven load and therefore dents and flaking of the raceway. This enhances durability and sliding characteristics of the raceway surfaces.
