... thrust roller bearings and hybrid ceramic thrust roller bearings. Using Hertzian contact theory, the contact stress calculation formulas for steel-steel and steel-ceramic line contacts are derived. A finite element analysis model of the bearings is developed to evaluate and analyze the contact stress...

...Xudong Zhao; Yimin Zhang Purpose This paper aims to evaluate the dynamic performance of hybrid roller bearings under lubricant contamination. Design/methodology/approach Some steel rollers in traditional cylindrical thrust roller bearings were replaced with ceramic rollers to assemble hybrid...

... of the tribofilm formation is still unclear. The purpose of this study is to characterize the chemical details of the tribofilm by using high-resolution approaching. Design/methodology/approach An ISO VG 100 mineral oil mixed with ZDDP was used in sliding tests on cylindrical roller bearings. Tribofilm...

...Wenjing Zhang; Wei Chen; Zhe Liu Purpose The aim of this study is to understand thermal effects and surface topography of roller bearings with misaligned load under combination of multifactors by an experimental method. Design/methodology/approach A series of orthogonal experiments would need...
