Improvement of Deep Groove Ball Bearing’s Performance Using a Bionic Textured Inner Race

Micro-textured surfaces have improved the tribological performance of contact surfaces under lubricated conditions; however, not practiced due to manufacturing challenges. In addition to simpler micro-pits or straight-trench type textures, sophisticated bioinspired textures on commercial radial ball bearings have been scarcely studied. In this work, Dendroaspis polylepis (Mamba snake) skin-type textures were fabricated on the inner race of FAG...
