Varieties of Snap ring

Snap rings, also known as retaining rings or circlips, come in a variety of types and styles to suit different applications. Some common varieties of snap rings include:

1. Internal Snap Rings: These are designed to fit into an internal groove or recess in a component. They are compressed when installed and expand to lock into place, providing a secure fit on the inside of the component.

2. External Snap Rings: External snap rings fit over the outside of a component, such as a shaft or bearing. They are expanded when installed and then compress to lock into an external groove or recess.

3. Axial Snap Rings: Axial snap rings are used to secure components axially, preventing them from moving in a linear direction. They are commonly used in bearings and other rotating components.

4. Radial Snap Rings: Radial snap rings secure components radially, preventing them from rotating or moving radially within a housing or assembly.

5. SP and NR Bearing Retaining Rings: These are common types of snap rings used specifically in bearing applications. They are designed to fit into grooves in bearing housings or shafts to secure the bearing in place.

6. WR, WRE, and SW Axial Retaining Rings: These snap rings are used for axial retention of components such as shafts and bearings. They have a unique design that allows for easy installation and removal.

7. BR, AR, and SB Internal Retaining Rings: These snap rings are designed for internal retention applications, such as securing components within a housing or assembly.

8. RW and RB Wire Retaining Rings: These are made from wire and are used for lightweight and compact retention applications.

It's important to note that the specific variety of snap ring needed will depend on the application, the size and shape of the components, and the required retention force. Manufacturers and suppliers can provide more detailed information and guidance on selecting the appropriate snap ring for a specific application.
