  • Friction torque of thrust ball bearings lubricated with ...

    2013-2-1 · Highlights Five wind turbine gear oils were selected. Density and viscosities were measured. Frictional behaviour of a thrust ball bearing (51107). A modified Four-Ball Machine was used and tests were performed between 150 and 1500 rpm. Operating temperatures and internal friction torque, power loss and heat evacuated are presented. Rolling and sliding friction torques were determined.

  • Friction | SKF

    The friction in a spherical plain bearing or rod end depends primarily on the sliding contact surface combination, the load and the sliding velocity. Because there are so many influencing factors that are not mutually independent, it is not possible to quote exact values for the coefficient of friction.
