  1. Function: The primary function of a bushing is to reduce friction and wear between moving parts, while also providing support and alignment. Bushings serve as a replaceable lining or a sleeve that fits into a housing or bore to support and guide a rotating or sliding shaft.
  2. Design: Bushings are typically made of metal, plastic, or composite materials. They have a hollow cylindrical shape with an inner diameter (ID) slightly larger than the diameter of the shaft they support, allowing for a close fit. The outer diameter (OD) is sized to fit snugly within the housing or bore.
  3. Types: Bushings come in various types, including plain or sleeve bushings, flanged bushings, split bushings, and spherical bushings. Each type is designed for specific applications and may have features such as lubrication grooves, flanges for mounting, or self-lubricating properties.
  4. Materials: Bushings are commonly made from materials such as bronze, brass, steel, aluminum, nylon, or polymer composites. The choice of material depends on factors such as load capacity, operating temperature, corrosion resistance, and lubrication requirements.
  5. Applications: Bushings are used in a wide range of applications across industries, including automotive, aerospace, industrial machinery, and consumer products. They are commonly found in suspension systems, steering components, electric motors, pumps, and hinges, among others.
  6. Installation: Bushings are typically press-fit or shrink-fit into the housing or bore using hydraulic presses, arbor presses, or other installation tools. Proper alignment and sizing are critical to ensure smooth operation and longevity of the bushing assembly.
  7. Maintenance: Bushings require periodic inspection and maintenance to ensure proper lubrication and functionality. Lubrication may be applied through grease fittings or oil passages, depending on the bushing type and application. Worn or damaged bushings should be replaced promptly to prevent excessive wear on mating components.
