Buy HITACHI EX100 120-5 SWING DEVICE SLEW BOX OIL SEAL (OEM HI 4424512) | Tonkee®

Material Composition: Oil seals are typically made from high-quality materials like rubber or elastomers, which exhibit excellent sealing properties and resistance to hydraulic fluids.

These materials are chosen for their durability and ability to withstand the harsh operating conditions of heavy machinery.

Precision Design: The HITACHI EX100 120-5 Swing Device Slew Box Oil Seal is precision-designed to fit snugly within the swing device assembly. This tight fit ensures that there are no gaps or spaces through which hydraulic fluid could escape.

Leak Prevention: The primary purpose of this oil seal is to prevent hydraulic fluid leakage. Any leakage can lead to a loss of hydraulic pressure, which can hinder the excavator's ability to perform its tasks effectively.

Longevity: Oil seals are expected to have a long service life, given the demanding nature of construction and excavation work. The HITACHI OEM oil seal is manufactured to meet these expectations, contributing to the overall reliability and uptime of the excavator.

The HITACHI EX100 120-5 Swing Device Slew Box Oil Seal is a critical component that ensures the proper functioning of the excavator's swing device.

Its importance can be summarized as follows:

Fluid Containment: By sealing off the hydraulic fluid, this oil seal ensures that the swing motor and other hydraulic components receive a consistent and uninterrupted supply of fluid. This is crucial for maintaining the excavator's operational efficiency.

Preventing Contamination: Oil seals also act as a barrier against external contaminants like dust, dirt, and debris. Keeping these contaminants out of the hydraulic system helps prevent damage to components and maintains the system's integrity.

Cost Savings: Effective seals can extend the lifespan of hydraulic components, reducing the need for frequent replacements and repairs. This contributes to cost savings for equipment owners and operators.

Safety: A well-maintained hydraulic system, including the proper functioning of the oil seal, is essential for the safety of operators and those working in the vicinity of the excavator. Leaking hydraulic fluid can create hazardous conditions on the job site.
