Stopperskiver

Stopperskiver, also known as stop discs or retaining discs, are mechanical components used in various engineering applications to prevent excessive movement or maintain a specific position of other parts. They typically consist of a disc-shaped component with an opening or slot designed to fit around a shaft or rod. Their primary function is to act as a physical barrier, limiting the travel of a component along an axis.

These components are often employed in assemblies where precise positioning is critical or where parts could otherwise become dislodged. For example, in some sliding mechanisms or pivot points, stopperskiver are used to define the end of travel, preventing a part from moving beyond a predetermined limit. They can also be used in conjunction with other fasteners, such as screws or pins, to provide an additional layer of security and prevent loosening or separation.

The design of stopperskiver can vary depending on the specific application and the load they are expected to bear. They can be made from a range of materials, including metals like steel or aluminum, as well as durable plastics. The method of attachment can also differ, with some being press-fit, threaded, or secured by set screws. Their simplicity and effectiveness make them a common solution for many motion control and assembly challenges.
