In order to reduce greenhouse gas emissions, low viscosity and small quantities of filling greases are used in rolling bearings for low toque. This causes lubrication conditions of rolling bearings more severe. Under such conditions, it is necessary to accurately predict the lubrication conditions to maintain the required functions of the bearings. Lubricating grease shows complex flow behavior inside tolling bearings. This makes understanding of grease lubrication difficult. This article introduces some of the research on the phenomena related to grease lubrication to predict the grease lubrication condition inside bearings.
