China HITACHI EX100 120-2-3-5 SWING DEVICE SLEW BOX MOTOR OIL SEAL 52 X 35 X 6 MM (OEM HI 0407705 FA 71467345) | Tonkee®

The primary purpose of the Hitachi EX100 120-2-3-5 swing device slew box motor oil seal is to prevent the leakage of lubricating oil from the swing device slew box motor.

The swing device is a crucial part of excavators, responsible for enabling the machine to rotate and perform tasks effectively. The oil seal serves as a barrier, ensuring that the lubricating oil remains contained within the motor, thereby maintaining proper lubrication levels and preventing damage due to friction and wear.

The oil seal has specific dimensions, measuring 52 x 35 x 6 mm. These measurements are critical to ensure a proper fit and effective sealing within the swing device slew box motor. The 52 mm outer diameter, 35 mm inner diameter, and 6 mm thickness are precisely engineered to meet the requirements of the machinery, providing a tight seal that prevents oil leakage.

The OEM (Original Equipment Manufacturer) part number for this oil seal is HI 0407705, and it is also identified with the reference number FA 71467345. These OEM details are essential for sourcing genuine replacement parts to ensure compatibility and performance consistency with Hitachi excavators. Using OEM parts like this oil seal helps maintain the integrity and reliability of the machinery.

The Hitachi EX100 120-2-3-5 swing device slew box motor oil seal plays a critical role in ensuring the smooth and efficient operation of Hitachi excavators. Here are some key points highlighting its significance:

Lubrication Maintenance: The oil seal prevents lubricating oil from escaping the swing device slew box motor.

Adequate lubrication is essential to reduce friction, heat, and wear on moving parts, ultimately extending the lifespan of the equipment.

Protection Against Contaminants: In addition to retaining oil, the seal acts as a barrier against external contaminants, such as dirt, dust, and moisture. These contaminants can be detrimental to the internal components of the motor, leading to costly repairs if not properly sealed.

Enhanced Performance: A well-maintained swing device motor with a reliable oil seal contributes to the excavator's overall performance and efficiency. Smooth rotation and precise control are essential for various construction and excavation tasks.

Minimizing Downtime: Regular inspection and replacement of worn or damaged oil seals can help minimize downtime by preventing unexpected breakdowns and ensuring the excavator's availability for ongoing projects.
