5. FAQ

Q: What specific Hyundai excavator models does XKAQ-00803 fit, and what is its main installation position?
A: This heavy-duty floating oil seal is designed exclusively for Hyundai large/heavy excavators, covering the R300LC-7, R300LC-9A, R305LC-7, R320LC-7, R320LC-9, R330LC-9A and other 30–35 tonnage models. It is installed in the final drive/travel motor reduction gearbox and track roller assemblies, responsible for sealing high-torque rotating parts in heavy-load digging and long-distance travel scenarios.

Q: Why choose GCR15 steel and NBR70 rubber for this heavy-duty seal, and what are their performance advantages?
A: The GCR15 bearing steel has extremely high hardness (58–62 HRC) and excellent wear resistance, which can withstand high impact loads and long-term friction in heavy excavators without deformation. The NBR70 rubber has higher hardness and oil resistance than standard NBR60, resisting high-pressure gear oil and hydraulic fluid erosion, and maintaining stable elasticity at 130°C high temperature, avoiding softening or aging in heavy-load continuous operation.

Q: What is the color, surface finish and structural feature of XKAQ-00803? Are there customized options?
A: The metal ring is silver-gray with a precision-lapped mirror sealing surface (Ra ≤ 0.2μm), no burrs or scratches. The rubber ring is black matte with a thickened rectangular cross-section for heavy load. The standard structure is a paired dual-ring assembly (2 metal + 2 rubber rings). Custom options include high-temperature brown HNBR rubber (150°C resistant) and anti-corrosion stainless steel rings for coastal or chemical-contaminated sites.

Q: What is the operating temperature range, pressure resistance and service life of this seal under heavy working conditions?
A: It operates reliably at -30°C to +130°C, adapting to extreme cold and high-temperature heavy-load environments. It withstands max 2.5MPa internal pressure, suitable for high-pressure final drive systems of heavy excavators. Under normal heavy construction conditions, the service life is 8,000–12,000 hours; in severe mining or rocky terrain, it reaches 5,000–7,000 hours, 20% longer than standard floating seals.

Q: Is XKAQ-00803 a genuine OEM part? What is the interchangeability with old and new models?
A: It is a 100% OEM equivalent replacement for Hyundai original XKAQ-00803, fully compatible with both old R-7 series (R300LC-7) and new R-9 series (R320LC-9/R330LC-9A) heavy excavators. It can directly replace the original seal without modification. Before installation, only check the groove wear; no additional processing is required.
