Rolling-element bearings consist of rolling bodies which move in races. They can be loaded radially or axially or in both of these directions. The basic forms are shown in Fig. 9.1. The rolling elements can be balls, rollers, tapered rollers, spherical rollers or needles (Fig. 9.2). These rolling bodies are positioned within a cage, which holds them at a set spacing. Futher forms of construction for ball-bearings are shown in Fig. 9.3.
