摘要： PROBLEM TO BE SOLVED: To provide a rolling device which hardly causes damage to a raceway surface and enables a long service life.
SOLUTION: Raceway surfaces 1a, 2a of a ball bearing are subjected to superfinishing and two types of shot peening. The shot peening in which substantially spherical ceramic particles having an average particle diameter of 200 μm or smaller are projected is applied to the raceway surfaces 1a, 2a subjected to superfinishing. Subsequently, the shot peening in which substantially spherical rubber particles having an average particle diameter of 1.5 mm or smaller are projected is applied to the raceway surfaces 1a, 2a. The rubber particle is formed of rubber on which an abrasive having an average particle diameter of 3 μm or smaller is dispersed. The surface roughnesses Ra of the raceway surfaces 1a, 2a subjected to these treatment are between 0.01 μm and 0.07 μm. The surface residual stress of the raceway surfaces 1a, 2a is between -1,400 MPa or larger and -900 MPa or smaller.
