Most bearings operate with a fluid film -- oil, another liquid, or a gas. By far the largest number of bearings are oil lubricated. The oil film can be maintained through pumping by a pressurization ...

Journal bearing design is complex. It involves optimizing clearances, bearing length, minimum film lubricant, viscosity, flow rate, and inlet slots. Design equations are available, but their solution ...

Lubricant evaluation was previously carried out based on experience and intuition. Today however, products are required to run more efficiently, longer, and faster. This requires a scientific approach ...
