Find the radial force, bearing length and tension bushing load for the object. These should be located on the side of the machine or in the owner’s manual.
Plug the numbers into the following equation:
oLm(p) = F/(l-f)di. The radial force equals F, the bearing length is l-f and the tension ID is di. The o stands for the sum of the force placed on the object. The L stands for the weight of the bottom load. The m stands for mass of the object. The p stands for pressure exerted on the load.
Solve the equation based on the numbers you added to the equation. The resulting number is the calculated bushing load of that object. You can calculate the bushing load of any object using the same formulas.
