    Low viscosity base oils are used for very high speeds. High viscosity base oils are used for high load applications. The viscosity of a typical roller bearing grease at +40 °C is between 15 and 500 mm²/s. NLGI grade Greases are divided into various consistency grades (NLGI grade). High consistency = stiff grease = high NLGI grade
