Calculating Grease Quantity, Frequency

15/8/2020· To calculate grease quantity, you need the bearing’s physical dimensions (primarily the outside diameter and width). Once you have these two measurements (in inches), you multiply them together and then multiply by 0.114. The resulting answer is the grease quantity in ounces. This formula can be used with metric measurements as well; just use
