A stop pin is a mechanical component designed to limit or stop the movement of sliding or rotating objects by coming into direct contact with them. Due to their frequent contact with other parts, stop pins are made with materials that boast high hardness and abrasion resistance. They can be secured in their mounting holes by press-fitting or screwing, and the contact point can be located on the head or the side, depending on the application.
Stop pins find applications across various fields, especially in machining. In this context, they are often used to mark the end of positioning for components like molds and pedestals. When paired with a stop bolt, the pin's head contacts the tip of the aligned bolt to halt movement at a specific point. In rotating elements, the interaction between the stop pin and the inner surface of a notch controls torque fluctuations.
Given their role in direct contact, stop pins are typically made from robust materials like S45C carbon steel, known for its high strength and suitability for quenching. The end face of a stop pin might be hardened, polished, and treated with trivalent chromate for enhanced durability. While the bolt type is common, variations include three-jawed designs with spring materials, offering additional holding functions, and other forms like spherical ends, resin-tipped, or press-fit models.
