NES understands the importance of determining how the design, material choices, and manufacturing differences combine to provide an empirical life for comparison to the theoretical calculated life. Through this information we are able to determine the life adjustment factors for each supplier. To determine the life adjustment factors the bearing is tested through sudden death (first-in-four) or classical test methods both of which provide failure data points that are vital in producing a weibull plot similar to the one depicted to the right.
Understanding the weibull plot and the data collected shows the relative difference or life adjustment from one supplier to the next. If a client understands their application well enough they are now able to determine the increase or decrease associated with the use of an alternate supplier.
