The effect of primary loading on fatigue life of cylindrical roller bearings
TL;DR: In this paper, an elastic perfect plastic analysis was performed to reveal the role played by the roller's crowning geometry, operating clearance, misalignment angle and operating loads on contact pressures distributions achieved between each roller and the corresponding inner and outer raceways.
