Product Description

This metallic precision connecting bushing is made with stainless steel as the base material. Through the stamping - forming process, it takes on a structure that includes a cylindrical body (with longitudinal slits) and a flat extension part (with small holes). After galvanization or oxidation surface treatment, it presents a silver - white metallic luster and a delicate texture.

 

The product has a compact size (length ranging from 25 - 40mm, outer diameter of the cylindrical tube from 8 - 12mm) and high precision (tolerance of ±0.1mm). Its core design takes into account both connection (fixed by bolts) and guiding (small holes compatible with wires) functions.

 

Thanks to its multi - form adaptability and durable characteristics, it is widely used in the internal connection of electronic devices, the assembly of home appliance circuits, automotive electronics assembly, and mechanical maintenance. It provides reliable precision connection solutions for multiple scenarios.

 

Moreover, its cylindrical body design ensures a stable fit for components, while the longitudinal slits offer flexibility for wire routing and adjustment. The flat extension part with small holes not only enables easy bolting but also provides additional stability during installation. The surface treatment not only enhances its aesthetic appeal but also effectively protects against environmental factors such as moisture and chemicals.
 

Core Values

 

• Integrated Functionality: A single component simultaneously meets the needs of connection, fixation, and guidance, streamlining the assembly process. It eliminates the need for multiple separate parts, reducing inventory management and assembly complexity.
• Multi - Scenario Applicability: Compatible with four major fields including electronics, home appliances, automotive, and machinery, it significantly reduces the replacement cost across different scenarios. Whether it's in a high - tech electronic device or a traditional mechanical equipment, this bushing can be seamlessly integrated.
• Efficiency and Quality Improvement: With high - precision dimensions (tolerance of ±0.1mm) and standardized surface treatment, it shortens the installation time by 30% and extends the service life of equipment (≥5 years). The consistent quality ensures fewer assembly errors and less maintenance over time.
• Cost Optimization: The lightweight nature of stainless steel (density of 7.9g/cm³) reduces transportation costs. The surface treatment extends the maintenance cycle, and the overall cost is 25% lower compared to ordinary steel parts. This makes it a cost - effective choice for both small - scale and large - scale production.
