Abstract
In this linear motion rolling guide unit, return passages are formed by sleeves fitted in return bores in the casing, and these sleeves are made elastically deformable, so that they can offset the slide resistance of rolling elements and secure the smooth rolling of the rolling elements. In this linear motion rolling guide unit, sleeves extending over the whole length of the return bores in the casing and forming return passages for cylindrical rollers are fitted in the return bores, and clearances, in which the sleeves can be elastically deformed, are provided between the inner surfaces of the return bores and the outer surfaces of the smaller-diameter portions of the sleeves. The sleeves are provided with slits extending in the longitudinal direction thereof, and both end portions of the sleeves are held in the return bores in the casing.
