Abstract
It is an object of the present invention to provide a linear bearing which is easy to manufacture and has sufficient mechanical strength, and its production method. A slider 1 guides a table or other movable bodies along a rail 2 and includes a thin ball plate 6 in which load ball channels 61 are formed to move balls 5 therein, and a thin mounting plate 7 adapted to secure the movable body. A molding material 8 such as resin or die cast alloy is molded to insert the ball plate 6 and the mounting plate 7 thereinto. The rail 2 is made of a metallic material 2 whose surface is hardened to a predetermined level when subjected to plastic deformation. During plastic deformation, the ball channels 23 are hardened to a predetermined level.
