>> Product Use
Reducing friction: They are installed between the loader bucket and its connecting components like the boom and bucket rod. Acting as a buffer, they decrease the direct contact and friction between metal parts. This helps lower the wear rate of the bucket and its connecting parts, prolonging their service life and reducing maintenance costs.
Maintaining stability: With high - precision matching to the pins and shafts, steel bushings minimize the clearance and shaking of the bucket during operation. This enhances the stability and accuracy of the bucket's movement, enabling more efficient and precise loading and unloading operations.
Absorbing shock: Steel bushings have a certain degree of elasticity, which allows them to absorb some of the shock and vibration generated during the loader's operation. This helps protect the bucket and other components from damage due to excessive shock, improving the overall reliability of the equipment.
Sealing and protecting: They can prevent dust, dirt, and other impurities from entering the internal parts of the bucket's connections. This protects the internal components from contamination and damage, ensuring the normal operation of the equipment and reducing the risk of malfunctions.
Maintaining dimensional accuracy: High - quality steel bushings have strict dimensional accuracy, which helps maintain the correct fit between the bucket and its connecting parts. This ensures the proper transmission of force and movement, improving the overall performance of the loader.

Alloy steel:
Composition: It contains various alloying elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), and manganese (Mn) in addition to the basic iron and carbon.
Properties: Alloy steel has high strength, excellent wear resistance, and good toughness. The addition of alloying elements improves its hardenability, allowing it to maintain high hardness and strength even after heat treatment. It also has better resistance to deformation under high - load conditions.
Application: It is widely used in the manufacture of loader bucket bushings that require high strength and wear resistance, especially in harsh working environments or when dealing with heavy - duty operations.
Carbon steel:
Composition: Mainly composed of iron and carbon, with a carbon content ranging from 0.12% to 2.0%. According to the carbon content, it can be divided into low - carbon steel, medium - carbon steel, and high - carbon steel.
Properties: Low - carbon steel has good plasticity and weldability but relatively low strength and hardness. Medium - carbon steel has a balance of strength, hardness, and toughness. High - carbon steel has high hardness and strength but lower plasticity and toughness.
Application: Medium - carbon steel is commonly used for loader bucket bushings in some general - purpose loaders due to its good comprehensive properties and relatively low cost. High - carbon steel may be used in specific applications where extremely high hardness and wear resistance are required.
