Zusammenfassung: | The present invention addresses the problem of providing a grease composition with sufficiently low dust emission for use in a clean room or other clean environment and with sufficiently high load bearing capacity for lubricating a motion guiding device that is incorporated into a large-scale clean robot. The present invention solves the problem by providing a clean-environment grease composition that comprises a base oil, a thickener, and an extreme-pressure agent wherein the kinematic viscosity of the base oil is 100 to 300 mm2/s at 40 DEG C, a lithium complex soap is contained therein as the thickener, and the content of the thickener is 10 to 40 mass% of the total composition. |
