The ball bearing cage (also known as a ball bearing retainer or ball separator – these are used interchangeably), is the component in a ball bearing that separates the balls, maintains the balls symmetrical radial spacing, and in most cases, holds the bearings together. Cages can also be utilized in providing lubrication by acting as a reservoir for oils, or by supplying a solid film via the cage material itself or a coating on the cage. The designer’s selection of the appropriate cage design for the application is essential in achieving the desired life and performance of the bearing. Ball bearing cages are guided by one of the available surfaces between the inner and outer rings. There are inner land riding retainers where the retainer’s bore slides, or is guided by, the O.D. of the inner ring, Outer land riding retainers where the O.D. of the retainer slides, or is guided by, the bore of the outer ring, and ball riding retainers where the retainers touch neither ring and is totally guided by the balls. Unfortunately, all cages produce frictional forces that increase the starting and running torque in the bearing due to their rubbing contact. As a result, cages are available in a variety of configurations and materials that enhance performance in torque sensitive applications, at higher speeds, or in extreme environments. Some designs are limited in use in certain types of bearings depending on the size and configuration of the bearing. However, there are four basic types of cages that are the most common, readily available, and will perform well in most applications. The four types of cages are the J-type, W-type, RJ-type, and TW-type. Each cage is described in detail below in addition to some of the other less commonly used ball bearing retainer types.
