PROBLEM TO BE SOLVED: To provide a rolling device being less susceptible to abnormal wear and seizure, having longer life, giving less flying particles and evaporating gas to external environment and being suitable for use in clean environment, and a grease composition. SOLUTION: The kinetic viscosity of a liquid fluorinated polymer constituting a base oil for a lubricant composition J is in the range of 50-450 mm<SP>2</SP>/sec at 40°C. The device is previously subjected to run-in rotation under reduced pressure before use. COPYRIGHT: (C)2003,JPO |
