Shaft Loading and Sealing Vs. Bearing Life Expectancy
Shaft loading is likely the top cause of premature bearing failure. There are two types of loading to consider: radial and axial. Radial loading is the perpendicular force applied to the shaft. Common causes of radial loading include misalignment of the shaft when mounted or use of items such as pulley and gears. Axial loading is the parallel force, or force applied along the same direction of the shaft. As radial and/or axial loading increases, bearing life shortens.
