Retaining Rings / WashersRetaining rings and washers are mechanical components that are used to hold other parts in place or to distribute loads. Retaining rings are circular rings that are installed in a groove on a shaft or other cylindrical part, and are used to hold bearings, gears, and other components in place. Washers are flat or slightly curved discs that are used to distribute loads and prevent bolts and other fasteners from pulling through or damaging the material they are attached to. Washers are available in many different sizes, materials, and designs to suit different applications. They are commonly used in conjunction with screws, nuts, and other fasteners to provide a secure and stable attachment.
