... modification factor is obtained against P/C ( P : equivalent bearing load, C : basic dynamic capacity ) under various contaminated lubrication conditions. rolling bearing rolling contact fatigue bearing life contaminated lubrication life calculation local stress Hiromasa Tanakat and Noriyuki...

... bearing life and the direction of measures to each factor are described, then the characteristics of KE bearings and KUJ7 steel are also described. rolling bearing rolling contact fatigue contaminated lubrication semi-high temperature temperature resistance retained austenite Masamichi...

... the test specimens were charged with a sufficient amount of hydrogen prior to testing. The test results concluded that brittle flaking is caused by the diffusion of hydrogen into the steel due to the decomposition of the grease by a tribochemical reaction. rolling bearing microstructural change...

... In recent years, the nonmetallic content of military and commercial aircraft has been steadily increasing; this trend is expected to continue for the next decade. In this study, nonmetallic materials have been evaluated for journal bearing and rolling bearing applications. Specifically, advanced...
