PROBLEM TO BE SOLVED: To provide a rolling device capable of more restraining smearing from being generated, and more prolonging lubrication life.SOLUTION: In a rolling device, a surface of a rolling element is regulated to bring an average surface roughness into Ra 0.08 μm or less by projecting a polishing particle dispersed with an abrasive grain onto a spherical elastomer, and a metal coating film containing zinc and tin is formed on at least one raceway surface in an inner member and an outer member. |
