What is a push ring?

A push ring is a mechanical component typically used in various machines and devices to provide a stopping point or to retain other parts in place. It is designed to allow for axial movement while preventing lateral displacement, often used in conjunction with other components like shafts or bearings. Push rings can be made from various materials, including metal and plastic, depending on the application requirements. Their design can vary, but they generally feature a simple, circular shape that fits into a groove or recess.
