Abstract
A method of manufacturing a linear motion guide unit having a slider mounted to a rail. The rail includes a top surface, a bottom surface and a pair of side surfaces. A liner overlying the rail is press-formed against a core which is lager than a combination of the rail and a thin plate member. The press-formed liner is placed inside a mold and molten metal is poured into a gap formed between the liner and the mold. After the metal cools to a hardened condition, the slider is removed from the mold and assembled on the rail with a gap defined between the top of the rail and an opposed surface of the slider. Oil is supplied to the gap to define an oil film between the rail and the slider.
