GREASE COMPOSITION FOR ROLLING APPARATUS AND ROLLING APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a grease composition for a rolling apparatus, exhibiting excellent lubrication property under high-temperature/high-speed conditions and to provide a rolling apparatus having a long life under high-temperature/high-speed conditions. SOLUTION: The grease composition for a rolling apparatus is obtained by mixing a base oil containing >50 mass % based on the total amount of the base oil of an aromatic ester oil with a specific diurea compound as a thickening agent. The rolling apparatus is obtained by rollably arranging a plurality of rolling elements between an inner member and an outer member and packing a space composed of the inner member, the outer member and the rolling elements with the grease composition for a rolling apparatus.
