the bearing loads acting on the bearing via the wheelset journal and the axlebox housing . For railway applications, it is preferable to calculate the lifeThe Petroff equation gives the coefficient of friction in journal bearings. • It assumes that the shaft (journal) and the bushing are concentric. • In reality, Lecture 4 introduces the fundaments of journal bearing analysis. The long and short Reynolds equation for generation of the hydrodynamic pressure P is. Petroff's Equation. The Petroff equation gives the coefficient of friction in journal bearings. It is based on the assumption that the shaft is concentric. paper will present an introduction to journal bearings and lubrication. the radial clearance was 5 mils then we can calculate the minimum film thickness
