Cylindrical Galvanized Hollow Bushing

Product introduction

Galvanized hollow bushing is a hollow cylindrical non-standard part with galvanized surface treatment. Its main body is usually made of metal pipes, and its surface is covered with a layer of zinc using electroplating or hot-dip plating. The product's primary function is to serve as an internal skeleton or sleeve that supports, positions, isolates or protects, installed in holes or between components of equipment. In practical applications, it is often used in assembly holes of mechanical structures to strengthen the hole wall, prevent wear, and accurately guide shafts or pins. For example, at the pin joints of wooden furniture, steel structure connections or construction machinery, bushings can effectively disperse the load, reduce pressure loss on the base material, and extend the service life of the hole.

 

At the same time, the inner hole can often be processed to precise dimensions as needed to ensure that the shaft parts it matches can rotate or slide smoothly. The zinc coating on the surface provides it with good anti-rust and corrosion resistance, making it suitable for indoor humid environments or outdoor general atmospheric conditions to delay the corrosion of the metal body. This characteristic makes it widely used in construction, agricultural machinery, storage racks and other occasions that have basic requirements for weather resistance. Generally speaking, galvanized hollow bushing is a universal mechanical component that has both structural strengthening and basic protection functions.

 

Product features

Excellent anti-corrosion performance: The dense zinc coating on the surface provides effective electrochemical protection for the metal matrix and can significantly resist the erosion of moisture and general corrosive media in the atmospheric environment, extending the service life of the bushing in humid or outdoor environments.

Enhanced structural support and wear resistance: As a rigid bushing installed in the base hole, it can withstand and disperse the radial pressure and friction from shafts, pins and other matching parts, effectively preventing the base hole wall from being deformed, worn or strained due to direct force, and protecting the main structure.

Precise positioning and guidance: The inner hole size can be precision machined to ensure a precise clearance fit or transition fit with the matching shaft, thereby providing reliable positioning and guidance and ensuring assembly alignment and smooth movement.

Easy installation and wide applicability: The standardized cylindrical shape design makes it easy to press in or tap to install. At the same time, the galvanizing process enables it to be well adapted to a variety of common materials (such as steel and some aluminum alloy structures), and is widely used in connection and reinforcement parts in construction, furniture, mechanical equipment and other fields.

FAQ

Q: What is the main function of galvanized hollow bushing?

A: It mainly plays three major functions: strengthening, protecting and positioning. Installed in the hole of the base body (such as steel plate, wood), it can enhance the strength of the hole wall, prevent the mating shaft pin from directly wearing the base body, provide precise guidance for the moving parts, and use the zinc layer to provide basic anti-rust protection.

 

Q: What should I pay attention to when installing?

A: The key to installation is to ensure it is firm, vertical and undamaged. Usually, a press is used to press in or a special installation tool is used. It is strictly forbidden to directly hit it with a hammer to avoid damaging the inner hole, outer wall or zinc layer of the bushing. Before installation, the base hole should be cleaned and the bushing and hole should have a proper interference fit.

 

Q: Can the inner hole size of the bushing be customized?

A: Yes. Standard products have regular inner diameter sizes, but manufacturers can usually provide non-standard customizations based on drawing requirements, including specific inner diameters, outer diameters, lengths, wall thicknesses, and zinc layer thicknesses to meet special mechanical design needs.
