» Lubrication of bearings at low temperatures

Mineral oils are often low VI oils. It should be noted that VI says nothing about the actual base oil viscosity at low temperature. For greases, a way to assess low temperature behaviour is to measure the friction torque of a small ball bearing packed with grease and rotated at 1 r/min at a set (low) temperature.
