Claims
- 1. A method of manufacturing a rolling bearing for rectilinear movement, comprising the steps of:
- (a) making a table and a bed of the bearing from thin metal plates, respectively, and cutting them so as to have predetermined dimensions;
- (b) bending said metal plates at predetermined portions due to plastic deformation so as to have a U-shaped cross section;
- (c) forming track grooves each having a V-shaped cross section in the metal plates due to cutting work and/or grinding work so that the depth of said track grooves is 20% to 50% of the thickness of said metal plates, thereby manufacturing the table and bed; and
- (d) assembling said table over said bed through a plurality of rolling bodies in said track grooves.
- 2. A method of manufacturing a rolling bearing for rectilinear movement, comprising the steps of:
- (a) making a table and a bed of the bearing from thin metal plates, respectively, and cutting them so as to have predetermined dimensions;
- (b) forming notched portions in said metal plates at respective edge portions of the portions which are later bent so as to have U-shaped cross section providing portions of track grooves;
- (c) forming track grooves each having a V-shaped cross section in said metal plates due to plastic deformation;
- (d) bending said metal plates at said notched portions so as to have U-shaped cross sections due to plastic deformation;
- (e) forming track surfaces by grinding said track grooves, except at least a bottom portion thereof to provide ground bearing surfaces and an unground oil pocket, each of said track grooves having a V-shaped cross section in said metal plates, thereby manufacturing the table and bed; and
- (f) assembling said table over said bed through a plurality of rolling bodies in said track grooves.
