This document provides a detailed methodology for calculating the equivalent radial load and lifespan of ball and roller bearings. Key equations are outlined, including mathematical formulas to determine load distribution under specific configurations like axial and radial forces. The text examines assembly methods such as angled contact setups (X and O arrangements) and their impact on bearing stress and efficiency. It emphasizes complex calculations for balancing external forces across bearings, offering guidelines for multi-load scenarios.
