Black cylindrical pins are positioning pins, which are used to fix the relative position between parts. It is an important auxiliary part for combined processing and assembly. Pins are generally used for connecting, locking parts or assembling and positioning, and can also be used as parts of safety devices.
The pin hole should be hinged, and the black cylindrical pin is fixed in the pin hole with a small amount of interference. Multiple disassembly and assembly will reduce the amount of interference and reduce the firmness of the connection and the positioning accuracy.
Black cylindrical pins are mostly made of high-quality carbon structural steel. Generally, C35 and C45 are mostly used as materials, but heat treatment is required. Bearing steel is selected for high strength requirements. 65Mn is mostly used for elastic cylindrical pins.

1.The structure is simple, the centering is good, the bearing capacity is high, the variable load and impact performance are good, but the mating surface processing precision is high.
2.Large disassembly and assembly force will scratch the mating surface, which is a non-detachable connection. When the interference is not large or when hydraulic assembly and disassembly are used, the connection is also detachable.
3.Wide range of applications. Used for positioning, connecting, and also as a safety pin.
