bearing for the sake of simplicity, many rolling element bearings also have internal and mounting clearances. Some types of bearings, such as angular contact, X-type (four-point contact), and tapered roller bearings, have little or no internal clearance, which helps to minimize clearance-related shaft runout.

Depending on the application, normal bearing operating temperatures in pumps range from 100°F to 180°F, with most running between 140°F and 160°F. Although grease is used in some vertical pumps, oil is the preferred lubricant in the majority of pump applications. Standard bearing oils in pumps remain effective to approximately 180°F...turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and wide use. Figure 1.2 shows a diagram of these two types of systems.
