Evaluation of Friction Torque of Rolling Bearing.
Journal of the Japan Society for Precision Engineering, 1996 This paper aims at establishing an accurate methodology to evaluate the friction torque of rolling bearing during the rotation of spindle. The technique adopted here basically depends upon the accurate measurement of change in the rotational spindle speed during free run by applying a reflective sensor system.

Friction Torque in Miniature Ball Bearings
LubricantsThe problem of estimation the friction torque in operating miniature ball bearings lubricated with oil or grease is a complex one. Generally, in an angular contact ball bearing (ACBB), various types of losses can appear including losses caused by kinematics in ball-race contacts (rolling, sliding and pivoting), losses between the cage and the balls and
