Retaining rings are essential components used to secure parts onto a shaft or in a bore. They are typically installed into a groove on the external or internal diameter of a cylindrical object. These rings act as a restraint, preventing the components from moving axially or radially. Retaining rings come in various forms, including external retaining rings, internal retaining rings, E-clips, and more, each designed for specific applications.

Types of Retaining Rings

There are two main categories of retaining rings: internal and external. Internal retaining rings fit inside a bore or housing, while external retaining rings fit around a shaft or on the outside of a cylindrical object. Within these categories, there are several styles of retaining rings, including snap rings, E-clips, spiral rings, and many more. Each type has unique features that make them suitable for different situations.

Snap Rings

Snap rings are the most common type of retaining ring and come in various designs, such as tapered or constant section. They are typically installed in grooves with the ends snapping into place, hence the name "snap ring." Snap rings provide a simple and cost-effective way to retain components in a bore or on a shaft.
