GREASE COMPOSITION AND ROLLING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a grease composition that has higher heat resistance and torque durability than those of conventional grease and a rolling device. SOLUTION: A polar group-including lubricant oil that has polar groups in the molecular structure is mixed with a non-polar lubricant oil to prepare a base oil. A lithium compound soap thickener including a fibrous material with a length of≥3μm and a fiber diameter of≥0.2μm is added to the base oil to give the grease composition. The grease composition is enclosed in a rolling device. COPYRIGHT: (C)2004,JPO
