摘要：
The widespread use of grease lubrication in high-speed spindle bearings has been limited by its insufficient life. An extended grease life is required to meet the increasing demand of machine tool applications. Dominant grease properties are determined to attain longer life at higher speeds for spindle bearings. Part of the process includes rheological pull-off and oil bleeding tests, defining active grease reservoirs. The validation has been successfully carried out in a series of angular contact ball bearing (ACBB) grease life tests. The selected grease that fits the defined parameters has shown long life at speed factor, 2 million nd(m).
