Grease lubricated ball bearings are strongly required to improve low torque and quietness, but influence factors of grease on these performances have not been clarified. In this study, we investigated the factors influencing these two performances. As a result, it was clarified that the viscous transition stress of grease has a great influence on low torque property. Regarding quietness, it was revealed that the particle diameter and Young's modulus of the thickener has a great influence.
