Abstract

PURPOSE: To reduce friction against spherical projection and to turn a rotation shaft smoothly by means that a disc made up of a specific substance suports the projection of the rotation shaft.
CONSTITUTION: A rotation shaft 12 is vertically held in a metal shell 11, which can turn freely. A spherical projection 14 including a steel ball 13 attached at the lower end of the rotation shaft 12 is put on a disc 17 located on a cover 16 which closes the bottom of the shell 11. In a thrust bearing for example, used for supporting a turn table of a racord player said disc 17 is made of metal ceramics like metal ceramic nitride silicon nightlight or titanium nitride, or metal ceramics oxide like alumina. This can make the disc 17 in sliding contact to the spherical projection 14 smoothly and restrict uneven rotation of the rotaion shaft 12 and friction deterioration
