...Motohiro Kaneta; Kenji Matsuda; Hiroshi Nishikawa The effects of thermal conductivity, heat capacity, thermal inertia, and slide-roll ratio (SRR) on point elastohydrodynamic lubrication (EHL) are discussed with engineering ceramics and steel by a non-Newtonian thermal EHL analysis. When the thermal...

..., and performance tests of hybrid ceramic and steel ball bearings under the extensive operating conditions including oil-air supply pipe length, bearing preload, lube interval, oil type, oil viscosity, nozzle design, and rotation speed have been conducted. The test results show that the bearing has the lowest...
