ABSTRACT:
This invention provides a structure of a nonmagnetic raceway assembly in which the raceway assembly itself is formed of a nonmagnetic material to improve the sliding performance and strength of the raceway surfaces. The nonmagnetic raceway assembly structure includes a pair of raceway bodies which have raceway forming surfaces made of a nonmagnetic metal material and which move relative to each other; and raceway layers adhering to the raceway forming surfaces to form raceway surfaces. The raceway layers are made of a nonmagnetic composite material and formed as a porous structure that can retain lubricating oil or lubricant. The raceway surfaces are disposed facing each other to form a raceway through which the rolling elements travel rolling.
