..., and so on Such load data can be fed into a bearing calculation program to size the bearing. Furthermore, the loads can be scaled up to represent future requirements. For example, if the existing data pertain to a 750-ton unit, and the new unit will have a load rating of 1,000 tons, the scale factor...
