OHKITA Dowel Pin

OHKITA Dowel Pin is a precision mechanical component belonging to the dowel pin group, manufactured by the OHKITA brand. In mechanical manufacturing, dowel pins play a crucial role in ensuring precise alignment between two or more parts when assembled.

OHKITA dowel pins typically have a solid cylindrical shape, machined with high precision in diameter and straightness.

Materials: OHKITA dowel pins are generally made from durable, wear-resistant, and high-hardness materials such as:

• Alloy Steel: Examples include GCR15, SUJ2 (bearing steel), SKD, SCM. These steels are usually heat-treated (quenched) to achieve high hardness (e.g., 58-62 HRC), increasing wear and deformation resistance.
• Stainless Steel: Examples include SUS304, to resist rust and corrosion, suitable for humid or chemical working environments.

Key Features

1. High Precision: This is the primary advantage of OHKITA dowel pins. They are manufactured with very tight diameter tolerances (usually just a few micrometers, e.g., -0.005 mm to -0.01 mm), ensuring perfect mating and high repeatability during assembly.
2. Durability and Wear Resistance: Thanks to high-quality heat-treated alloy steel and/or stainless steel, OHKITA dowel pins offer superior hardness, excellent load-bearing capacity, and effective wear resistance, helping to extend product lifespan.
3. Diverse Materials: The ability to choose between bearing steel and stainless steel allows users to select pins suitable for their working environment (dry, humid, corrosive).
4. Flexible Design: OHKITA provides various types of pins with different head shapes, diameters, and lengths to meet diverse application needs. Some may feature additional functionalities such as air vents or insertion guide tip shapes for easy installation.

5. Wide Application: OHKITA dowel pins are used in almost all industries requiring high precision, such as molds, jigs and fixtures, automation machinery, electronic devices, automotive, aerospace, and robotics.

OHKITA Dowel Pin is an indispensable component in many modern mechanical and manufacturing systems. With high precision, superior durability, and flexible customization in material and size, they play a pivotal role in ensuring perfect mating, enhanced reliability, and performance of products and assembly lines.
