OEM HITACHI EX60-5 SWING DEVICE SLEW BOX PIN (OEM HI 4397249) | Tonkee®

The HI 4397249 swing device slew box pin is a precision-engineered component that is designed to endure the rigorous demands of construction and excavation work.

It is a crucial part of the slew mechanism, which allows the excavator to pivot or swing its upper structure horizontally. This is essential for accurate positioning of the excavator's boom and bucket during digging, loading, and other tasks.

Material and Construction:
The pin is typically constructed from high-strength alloy steel or a similar durable material. It is engineered to withstand heavy loads, extreme forces, and continuous movement. The choice of material ensures that it maintains its structural integrity even under intense working conditions.

Size and Dimensions:
The dimensions of the HI 4397249 pin are specific to the Hitachi EX60-5 excavator model. It is designed to fit precisely within the excavator's slew mechanism, ensuring smooth and efficient rotation of the upper structure. The pin's length, diameter, and other dimensions are carefully engineered to meet the manufacturer's specifications.

Function:
The primary function of the swing device slew box pin is to act as a pivot point within the excavator's slew mechanism.

It connects various components of the slew system, allowing them to rotate around this central point. When the operator controls the excavator's swing motion, hydraulic systems activate, causing the upper structure to rotate on this pin. This rotation is crucial for the excavator to reach and operate at different angles, making it a versatile tool on construction sites.

Compatibility and OEM:
The HI 4397249 pin is an OEM (Original Equipment Manufacturer) part, which means it is designed and produced by Hitachi to meet the highest quality and performance standards. Using OEM parts like this ensures the excavator's reliability, longevity, and optimal performance. It also maintains the manufacturer's warranty and support.

Maintenance and Replacement:
As a critical component of the excavator's slew system, regular maintenance is essential to ensure the HI 4397249 pin continues to function correctly. Lubrication and inspection should be carried out as per the manufacturer's recommendations. Over time, due to wear and tear, the pin may need to be replaced to maintain safe and efficient excavator operation.
