Study on Friction Torque of C_(7046112) Bearing

The influences of different axial load, rotative speed and lubricants on the friction torque of C7046112 bearing were studied under atmosphere in this paper. The results shown that the relation between axial load of bearing and friction torque is not monotonic function but periodical variation. When the optimum parameters are selected, the comprehensive consideration must be made based on kinds of factors, the smaller friction torque does not mean the better effect.
