Product Description

The cylindrical pin stands as a staple in mechanical connectivity, boasting a rich description that follows:

1, Basic Definition and Function

A cylindrical pin, crafted from robust metal or versatile plastic, takes on an elongated, cylindrical shape. It serves as an indispensable connector, adeptly inserted between components to ensure seamless connection, precise positioning, and efficient power transmission. Utilizing a slight interference fit, it becomes firmly secured within its intended hole, making it essential for part fixation, power conveyance, or as a crucial positioning element.

2, Main types and characteristics

Cylindrical pins come in a diverse array of types, each tailored with unique characteristics for specialized applications:

1. Ordinary cylindrical pin:

• Features: Boasting a straightforward design, these pins deliver excellent neutrality and impressive load-bearing strength.

Application: Ideal for high-neutrality requirements, commonly found in machinery, automotive industries, and power tools.

2. Internal thread cylindrical pin:

• Features: Equipped with an internal thread, these pins facilitate easy assembly/disassembly. While they offer moderate positioning accuracy, they excel in terms of installability.

Application: Perfect for positions demanding regular assembly/disassembly.

3. Elastic cylindrical pin:

• Features: Designed with elasticity, a hollow center, and side slots, these pins offer effortless assembly. They can be repeatedly disassembled without compromising the inner hole's integrity, making them ideal for complex disassembly scenarios.

Application: Suited for applications requiring frequent disassembly and minimal positioning accuracy.

4. Perforated pins:

• Features: Sporting holes on the pin body, these pins can be quickly locked and unlocked using an open mouth pin, ensuring easy disassembly.

Application: Best for applications like hinges that demand frequent connection and disassembly.

3, Materials and Standards

Crafted from a variety of materials like stainless steel (SUS304, 316), carbon steel (C35, C45), and bearing steel (Gcr15), cylindrical pins offer distinct mechanical and corrosion-resistant attributes. Choose based on specific environmental and usage needs.

Adhering to national and international standards, such as GB119 and GB120, these pins meet rigorous technical specifications concerning dimensions, tolerances, and materials, guaranteeing unmatched quality and interchangeability.

4, Installation and usage precautions

1. Preparation before installation:

Ensure the pin hole is perfectly hinged to meet the required size, shape, and surface smoothness for optimal cylindrical pin performance.

A light application of lubricating oil on the pin can significantly reduce friction and wear during installation.

2. Installation method:

Position a copper rod against the pin's end face and gently guide the cylindrical pin into its designated hole.

Alternatively, utilize specialized tools, such as a C-clip, to press the pin smoothly into place.

3. Precautions for use:

Due to the high disassembly force, cylindrical pins might scratch mating surfaces, thus classifying them as non-removable connections. Opt for elastic pins or those designed for multiple disassemblies when frequent removal is anticipated.
