Product Details
This product is a high-precision cylindrical pin (including solid pins and hollow pins), which is a core basic fastener used for positioning, connection or locking in mechanical manufacturing and assembly. It is made of high-quality alloy structural steel or stainless steel and is formed through precise grinding and heat treatment processes. It can achieve precise positioning and reliable connection between components, and is widely applicable to various precision mechanical and steel structure assembly scenarios.
Structural form: It is divided into solid cylindrical pins and hollow cylindrical pins. The solid pins have stronger load-bearing capacity, while the hollow pins are more lightweight and easier to disassemble. The ends are mostly designed as chamfers or arcs, which facilitate the guiding installation.
Material properties: The core materials include 40Cr, 45# steel, and 304/316 stainless steel, etc. The alloy steel models have high strength and good toughness, while the stainless steel models have outstanding corrosion resistance. You can choose flexibly according to the usage environment.
Precision standards: Strictly follow GB/T 119, ISO 2338, etc. standards for production. The surface roughness is low, the size consistency is good, and it can achieve interference fit or transitional fit to ensure the stability of the connection.
Appearance distinction: The surface presents metallic silver-gray or black. The solid pins are of a full cylindrical solid structure, and the end of the hollow pins shows an internal hole, which facilitates quick identification of the model and purpose at the site.
High positioning accuracy: Both the cylindrical surface and the end face have undergone precise grinding processing. The coaxiality and dimensional tolerance are controlled at the micrometer level, ensuring the repeat positioning accuracy of the connected components and meeting the assembly requirements of precision equipment.
Strong shear resistance: The solid pins are made of high-strength alloy steel and undergo quenching treatment, which gives them excellent shear resistance and compression resistance. They can withstand large lateral loads and prevent connection failure.
Easy installation and disassembly: Some models adopt hollow structures or chamfered designs, and with the help of special tools, they can be quickly assembled and disassembled. At the same time, they are convenient for later maintenance and component replacement, reducing operation and maintenance costs.
Corrosion-resistant, wear-resistant and durable: Optional stainless steel materials or surface hardening, blackening, galvanization and other treatment processes can be selected. They can maintain stable performance in humid, corrosive or high-maintenance environments, extending the product's service life.
Wide adaptability: Multiple specifications of diameters, lengths and solid/hollow models are available for selection. They can be compatible with different materials and thicknesses of components for assembly, meeting the diverse industrial scene requirements.
Precision mechanical manufacturing: Components positioning and shaft connection for machine tools, automation equipment, and instruments and meters, ensuring transmission accuracy and operational stability.
Molds and tooling fixtures: In injection molds, stamping molds, and tooling fixtures, as positioning pins to achieve precise alignment of mold cavities and inserts, improving product forming accuracy and production efficiency.
Automobile and construction machinery: Applied to components of engines, transmissions, chassis, and construction machinery frames for locking and positioning, capable of withstanding vibration and impact loads, ensuring equipment operation safety.
Electronic and electrical equipment: Small-sized cylindrical pins for positioning and fixation of precision electronic components and connectors, meeting requirements for miniaturization and high-precision assembly.
Steel structures and hardware assembly: As connecting pins in furniture, doors and windows, and steel structure supports, achieving hinge or fixation between components, with both strength and assembly flexibility.
