Hot sale HITACHI EX60-3-5 SWING DEVICE SLEW BOX MOTOR OIL SEAL 68 X 48 X 12 MM (OEM HI 4395197) | Tonkee®

68 mm: This is the outer diameter of the oil seal. It determines the size of the seal and how it fits within the motor assembly.

A snug fit is essential to prevent oil leakage and maintain the lubrication of internal components.

48 mm: This dimension refers to the inner diameter of the oil seal. It determines the size of the opening through which the motor shaft passes. A proper inner diameter is crucial to ensure that the oil seal effectively prevents oil from escaping while allowing the motor shaft to rotate freely.

12 mm: The 12 mm measurement is the thickness or width of the oil seal. This dimension is essential as it determines how effectively the seal can prevent oil from leaking out of the motor assembly and contaminants from entering it.

Now, let's discuss why this oil seal is of great importance in the context of the excavator:

Seal Function: The primary function of this oil seal is to prevent hydraulic oil from escaping the swing device slew box motor assembly. Hydraulic oil is essential for powering the excavator's movements and functions. Without an effective seal, oil leakage can occur, leading to a loss of hydraulic pressure, reduced efficiency, and potential damage to internal components.

Contaminant Protection: In addition to retaining hydraulic oil, the oil seal also acts as a barrier against contaminants such as dust, dirt, and moisture.

These contaminants can be detrimental to the internal components of the swing device motor. A properly sealed motor is critical for the excavator's reliability and durability.

Maintenance and Longevity: Regular maintenance and replacement of worn or damaged oil seals, like the Tonkee® OEM HI 4395197, are essential for prolonging the lifespan of the swing device slew box motor. Preventing oil leaks and contamination helps reduce maintenance costs and downtime.

Efficiency: Maintaining proper oil levels and preventing leaks ensures that the swing device motor operates efficiently. Efficient operation is essential for the excavator's productivity and performance on job sites.

Safety: Maintaining hydraulic oil within the system is not only crucial for the excavator's performance but also for safety. Sudden hydraulic failures due to oil leaks can result in accidents and injuries on the job site.
