ABSTRACT:
In a rolling bearing for rectilinear movement which is made by thin steel plates, the thickness of thin steel plates of table and bed are set to be thicker than those of conventional ones in order to provide rigidity, then the steel plates are formed due to press forming so as to have U-shaped cross sections. Track grooves each having a V-cross section are formed in the side walls of the table and bed. The V-shaped track grooves are subjected to cutting work and heat treatment and thereafter they are ground in order to improve the accuracy. Thus, it is possible to provide a cheap and light-weight rolling bearing for rectilinear movement which has high accuracy and high rigidity and is fitted for mass production.
