GREASE COMPOSITION AND BEARING WITH SEALED GREASE |
摘要 |
PROBLEM TO BE SOLVED: To provide a grease composition elongating the life of lubrication at an applied position when used at a high temperature, and further to provide a bearing with a sealed grease in which the grease composition is sealed. SOLUTION: This grease composition is obtained by formulating a thickener and an amide-based wax with a base oil. The amide-based wax has >=80 deg.C melting point, and an ability for preventing the oxidation of the base oil, and the formulated proportion based on the whole grease composition is 0.5-10 wt.%. The base oil of the grease composition is at least one kind selected from an ether-based oil, an ester-based oil and a synthetic hydrocarbon oil, and has 20-150 mm<2> /s kinematic viscosity at 40 deg.C. The thickener of the grease composition is a urea-based thickener, and the proportion of the formulated thickener based on the whole grease composition is 5-30 wt.%. |
