The actual operating viscosity, ν, of the lubricant can be determined from the ISO viscosity grade of the oil, or the grease base oil, and the operating temperature of the bearing . You can determine the rated viscosity, ν 1 , from diagram 2 , using the bearing mean diameter, d m = 0,5 (d + D) [mm], and the rotational speed of the bearing, n [r/min].
