Product Description

Cylindrical pins stand as a quintessential element in mechanical connectivity. Below is an in-depth portrayal of their characteristics and applications:

1, Basic Definition and Function

Cylindrical pins, crafted in metal or plastic, exemplify the perfect elongated shape designed to seamlessly integrate between connecting components, ensuring connection, precise positioning, and efficient power transmission. These pins typically employ a slight interference fit to secure within a hole, serving paramount roles in part stabilization, power conveyance, or as pivotal positioning elements.

2, Main types and characteristics

Cylindrical pins come in diverse types, each tailored for specific applications and distinguished by unique features:

1. Ordinary cylindrical pin:

• Features: With a straightforward structure, these pins boast excellent neutrality and impressive load-bearing prowess.

Application: Ideal for high-neutrality demands, evident in machine tools, automotive industries, and power tools.

2. Internal thread cylindrical pin:

• Features: Equipped with internal threading, this variant simplifies disassembly and assembly, offering reduced positioning precision yet effortless handling.

Application: Perfect for areas necessitating recurrent disassembly and installation.

3. Elastic cylindrical pin:

• Features: These pins are elastic and hollow, with expertly crafted slots on the sides, enhancing assembly ease. They endure multiple disassemblies without interior hole damage, making them apt for challenging disassembly scenarios.

Application: Best for frequent disassembly needs with minimal positioning precision demands.

4. Perforated pins:

• Features: Characterized by holes within the pin body, these allow for secure locking with open mouth pins, promoting straightforward disassembly.

Application: Particularly suitable for areas like hinges, where repeated disassembly and re-connection are common.

3, Materials and Standards

Cylindrical pins are fabricated using a spectrum of materials, including stainless steel (e.g., SUS304, 316), carbon steel (e.g., C35, C45), and bearing steel (e.g., Gcr15). Each material lends distinct mechanical attributes and corrosion resistance, enabling selection based on specific environmental and application requirements.

Moreover, cylindrical pins adhere to established national or international standards, such as GB119 (ordinary pins) and GB120 (internally threaded pins). These standards meticulously stipulate dimensions, tolerances, and material specifications, ensuring quality and interchangeability.

4, Installation and usage precautions

1. Preparation before installation:

Ensure the pin hole is appropriately hinged to align with required dimensions, shapes, and surface smoothness to accommodate the cylindrical pin.

A light coat of lubricating oil is recommended on cylindrical pins to minimize friction and wear during the installation process.

2. Installation method:

Use a copper rod on the pin's end face and gently guide the cylindrical pin into the hole with precision.

Alternatively, employ specialized tools like a C-clip to securely press the cylindrical pin into the hole.

3. Precautions for use:

Cylindrical pins possess a significant disassembly force, potentially marring mating surfaces, thus categorizing them as non-removable connections. For frequent disassembly needs, opt for elastic cylindrical pins or alternatives that allow repeated disengagement without compromising integrity.
