What does B10 life mean

[LaChristian]

B10 life is defined as: the operating time point of a product. After reaching this time point, it is expected that 10% of the products will experience failures. For automotive products, B10 is generally used to indicate the reliability of vehicles. Initially, B10 was applied to bearings, where 'B' stands for the first letter of 'Bearing', and '10' represents ten percent. More information about B10 life is as follows: Engine B10 life: Represents reliability. Taking the ISZ-13L engine equipped on the Tianlong flagship as an example, its B10 life reaches 1.6 million kilometers, meaning there is a 90% probability that this engine can operate normally up to 1.6 million kilometers. Purpose of B10 life: B10 life was originally used to describe the reliability and lifespan of bearings. During long-term usage, it was observed that the reliability of bearing products gradually declines with prolonged operation. For instance, if a batch of 100 bearings starts operating simultaneously, after extended operation, the bearings will enter a high-failure period, and beyond a certain time point, almost all bearings will begin to fail.
