The Slew Box Gear Planetary 1 is an essential part of the swing system in an excavator.
It is responsible for transmitting power from the hydraulic motor to the upper structure's swing bearing, which, in turn, enables the machine's 360-degree rotational movement. This functionality is crucial for an excavator's versatility, as it allows the operator to position the bucket or attachment accurately.
OEM Part Number HI 3069725:
The part is specifically designed and manufactured by HITACHI, one of the leading companies in heavy machinery and construction equipment. The OEM part number, HI 3069725, is a unique identifier that ensures compatibility and quality with HITACHI machinery models, including the EX100 120-5.
Material and Durability:
The Slew Box Gear Planetary 1 is typically constructed from high-strength materials, such as hardened steel or alloy, to withstand the extreme forces and stresses encountered in heavy construction applications. These materials provide the necessary durability to ensure a long service life, even under harsh operating conditions.
Manufacturing and assembly of this component require precision engineering to ensure optimal performance. The gear teeth, bearings, and other internal components must be machined to exact tolerances to guarantee smooth and efficient operation. Any imperfections in these components can lead to premature wear and reduced performance.
