In this paper a method for experimental determination of frictional torque in radial ball bearings is proposed. For this purpose, an experimental stand is designed and manufactured which allows experimental determination of the frictional torque. A mathematical model is presented which allows the determination of frictional torque in bearings, namely the torque due to liquid lubrication and the torque due to rolling. This mathematical model is processed and numerical data are obtained, by theoretical method, which are compared with those determined experimentally. The obtained results are presented and discussed in the paper.

A mathematical model is presented which allows the determination of frictional torque in bearings, namely the torque due to liquid lubrication and the torque due to rolling. This mathematical model is processed and numerical data are obtained, by theoretical method, which are compared with those determined experimentally. The obtained results are presented and discussed in the paper.
