Sleeve Bushing

SKU :

A Sleeve Bushing is a type of mechanical component that is used to reduce friction between two moving parts. It is a cylindrical bushing that is designed to slide over a shaft or pivot point, providing a smooth surface for the shaft to rotate on. Sleeve bushings are typically made from materials such as bronze, steel, or plastic, and they can be self-lubricating, which reduces the need for additional lubrication.

Sleeve bushings are commonly used in various industries, including machinery, automotive, aerospace, and consumer products. They are a cost-effective alternative to more complex bearing systems and can provide a low-friction surface for rotating shafts, which reduces wear and extends the lifespan of the equipment.

One of the benefits of sleeve bushings is their simplicity, as they do not have any moving parts, making them easy to install and maintain. Additionally, they can handle high loads and speeds, making them ideal for heavy-duty applications. However, sleeve bushings can be prone to wear over time, and they may require periodic replacement or maintenance to ensure optimal performance.

The specification of sleeve bushings can vary depending on the application and requirements. The material of a sleeve bushing is chosen based on properties such as resistance to wear, corrosion, or temperature. Sleeve bushings can be made from various materials like bronze, steel, or plastic. The size of the bushing is specified by its inner and outer diameter and length, which depends on the size of the shaft or pivot point it is designed to fit over, as well as the space available in the application.

Tolerance is an important factor when specifying sleeve bushings as it determines the allowable deviation from the specified dimensions. Load capacity, lubrication, and operating conditions are other specifications that may be considered. Load capacity specifies the maximum load that the bushing can support without deforming or failing. Lubrication may be necessary to reduce friction and prevent wear in some applications. Some sleeve bushings may be self-lubricating, reducing the need for additional lubrication. Finally, the operating conditions of the application, such as temperature and exposure to corrosive substances, may also be considered when specifying a sleeve bushing to ensure optimal performance.
