Excavator bucket bushing.
Reduce wear:
When the excavator is working, there will be frequent relative movements between the rocker arm and connecting arm and other parts. The bushing is installed at these connection parts, which can convert the direct friction between the parts into friction between the bushing and the parts. Since the bushing is usually made of wear-resistant materials, it can effectively reduce the wear of the connecting parts, extend the service life of the parts, and reduce the maintenance cost and replacement frequency.
Buffering and shock absorption:
Excavation operations will generate vibration and impact. The bushing can play a buffering role, absorb and disperse these vibration and impact energy, and reduce their impact on the overall structure of the excavator. It can not only protect the connecting arm, rocker arm and other parts, but also reduce the adverse effects on other systems of the excavator such as the hydraulic system and the electrical system, improve the stability and reliability of the equipment, and ensure the normal operation of the excavator.
Ensure connection accuracy and stability:
Accurate component connection is crucial to the operating accuracy of the excavator. The bushing can ensure that the connection gap between the rocker arm and the connecting arm is kept within a reasonable range, so that the parts maintain an accurate relative position during the movement, make the excavator's movement more accurate and stable, and improve the efficiency and quality of the excavation operation. For example, when performing fine excavation and leveling operations, the excavation depth and angle can be better controlled.
Easy to repair and replace:
Compared with directly replacing expensive large parts such as rocker arms and connecting arms, it is more convenient and less costly to replace bushings after they are worn or damaged. When there is a problem with the bushing, it can be replaced by simply removing it without large-scale repair or replacement of the entire connection structure, which can effectively shorten the maintenance time and improve the utilization rate of the equipment.

Raw material preparation
Material selection: Select appropriate materials according to product performance requirements.
Inspection: Strictly inspect the purchased raw materials to check whether the composition, hardness, metallographic structure, etc. of the materials meet the requirements to ensure the quality of the raw materials.
Cutting: According to the design size, use cutting machines and other equipment to cut the raw materials into suitable blanks, determine the length, diameter and other dimensions of the blanks, and provide a basis for subsequent processing.
Forming processing
Turning: Clamp the blank on the lathe and use turning tools to process it, accurately cut out the outer diameter, inner diameter, length and other dimensions of the bushing to ensure dimensional accuracy and surface roughness. During the turning process, multiple passes may be performed as needed to gradually meet the design requirements.
Drilling (some bushings with special requirements): According to the design of the bushing, it may be necessary to drill holes in specific locations, such as holes for installing oil channels, locating pins, etc. Use drilling machines and other equipment to accurately drill the corresponding holes according to the requirements of the design drawings.
Heat treatment
Quenching: Select a suitable quenching process according to the material and performance requirements of the bushing. The formed bushing is heated to a certain temperature and then cooled rapidly to improve the bushing's hardness, strength, and wear resistance.
Tempering: Tempering is usually required after quenching to eliminate quenching internal stress, stabilize the structure and size, improve toughness, and prevent the bushing from cracking or deformation during use.
Finishing
Grinding: Grind the inner and outer surfaces of the bushing, use grinding equipment and abrasives to further reduce surface roughness, improve surface accuracy, and make the bushing fit tighter and smoother.
Polishing: Through the polishing process, the bushing surface can achieve a higher finish and remove tiny scratches and burrs on the surface, which can not only improve the appearance quality, but also reduce friction resistance, which is conducive to the installation and use of the bushing.
