The swing device slew box plate thrust spacer SUN 2 is an integral component within the swing system of the Hitachi EX100-1 and EX120-1 excavators.
Its primary purpose is to facilitate the smooth and controlled rotation of the excavator's upper structure, which includes the cab, engine, and boom, allowing for precise digging, loading, and positioning of materials. This component is a part of the slew box assembly and contributes to the overall stability and performance of the machine during operation.
Construction and Materials
The thrust spacer SUN 2 is a meticulously engineered component designed to withstand the harsh operating conditions commonly encountered in construction and excavation work. It is manufactured to exacting standards using high-quality materials to ensure durability and longevity. Typically, these spacers are constructed from hardened steel or other robust alloys that can withstand the substantial loads and stresses placed on them during excavator operation.
Dimensions and Specifications
The precise dimensions and specifications of the thrust spacer SUN 2 (OEM HI 4195372) are critical for its proper function and compatibility with the Hitachi EX100-1 and EX120-1 excavators. These specifications may include the outer and inner diameters, thickness, and any other relevant measurements that ensure a precise fit within the slew box assembly. Accurate dimensions are essential to maintain the integrity of the swing system and prevent excessive wear and tear.
Installation and Maintenance
The installation of the thrust spacer SUN 2 should be performed by experienced technicians or mechanics who are familiar with the excavator's swing system.
Proper installation ensures that the component functions correctly and contributes to the machine's overall performance and safety. Additionally, routine maintenance checks should be carried out to inspect the spacer for signs of wear, damage, or corrosion. Regular maintenance is essential to prevent potential issues and extend the lifespan of the component.
Compatibility and OEM Specifications
The thrust spacer SUN 2 is an OEM (Original Equipment Manufacturer) component, bearing the part number HI 4195372, which is specific to Hitachi excavators, including the EX100-1 and EX120-1 models. It is essential to use genuine OEM parts to maintain the excavator's reliability, efficiency, and safety. Using non-OEM or substandard components can lead to premature failure and costly repairs.
Significance in Excavator Operation
The swing system, including the thrust spacer SUN 2, is a critical component in an excavator's functionality. It allows the upper structure of the machine to rotate horizontally, providing the operator with the necessary maneuverability to perform various tasks accurately and efficiently. The smooth and precise operation of the swing system ensures that the excavator can effectively dig, lift, and deposit materials, contributing to increased productivity on the construction site.
