They are usually unloaded or subjected to very small loads. The number is not less than two. They are distributed in the direction of symmetry of the overall structure of the connected parts. The length is about 1 to 2 times the small diameter.


At present, cylindrical pins are mostly made of carbon structural steel. Generally, the materials are mostly C35 and C45, other stainless steel and special alloy materials can be negotiable,heat treatment is required. Bearing steel is selected under high strength requirements.
