China HITACHI EX200-5 SWING DEVICE SLEW BOX PIN PLANETARY 2 (OEM HI 4336925) | Tonkee®

The swing device slew box pin planetary 2 is designed and manufactured by Hitachi, the renowned heavy machinery equipment manufacturer.

It is an original equipment manufacturer (OEM) part, which means it is produced by the same company that built the excavator, ensuring compatibility and high-quality performance. This part is specifically designed for the Hitachi EX200-5 excavator model.

At the heart of this component lies its role in the excavator's swing system. The swing system is responsible for enabling the excavator to rotate its upper structure, which is pivotal for its operation. This rotation allows the excavator to reach different areas without having to reposition the entire machine, making it a versatile and efficient tool for tasks such as digging, trenching, and material handling.

The planetary 2 pin in the swing device slew box is a key component that facilitates this rotation. It forms an integral part of the system's overall design and functionality. This pin is engineered to withstand the immense forces and stresses encountered during the excavator's operation, including the weight of the upper structure, the load being lifted, and the resistance encountered while digging.

The OEM specification for this component ensures that it meets the highest quality standards. Hitachi engineers have carefully designed the pin to exacting specifications, considering factors such as material strength, dimensions, and tolerances. This attention to detail ensures that the pin can withstand the rigors of heavy-duty excavation work, contributing to the excavator's overall reliability and longevity.

Material selection is a critical aspect of the OEM specification for this component.

The pin is typically made from high-strength alloy steel, which offers excellent durability and resistance to wear and tear. This choice of material ensures that the pin can endure the continuous load cycles and abrasive conditions it encounters during excavation operations.

The dimensions and tolerances of the pin are meticulously specified to ensure a perfect fit within the swing device slew box. Precision machining techniques are employed in the manufacturing process to achieve the required levels of accuracy. This precision is crucial to prevent play or excessive wear between moving parts, which could compromise the excavator's performance and safety.

Furthermore, the OEM specification also includes surface treatments or coatings to enhance the pin's corrosion resistance. This is particularly important because excavators are often used in harsh outdoor environments where they are exposed to moisture and other corrosive elements. The corrosion-resistant properties of the pin contribute to its long-term reliability and maintenance.
