5. FAQ

Q: What color is the rubber component, and are there alternative material options for extreme working conditions?
A: The standard rubber color is black, which provides optimal UV and ozone resistance for general construction applications. We also offer three upgraded alternatives for extreme environments: brown high-temperature NBR70 for desert or high-heat regions (withstanding up to 130°C), green chemical-resistant HNBR for waste treatment plants or sites with hydraulic fluid contamination, and high-strength ductile iron metal rings for heavy mining applications requiring greater impact resistance. The standard design features a square rubber cross-section; we also provide low-friction PTFE-coated metal rings for high-speed travel motor applications.

Q: What does this assembly include, and what are the critical installation steps and precautions?
A: It is a complete, pre-matched assembly containing 2 precision-ground metal rings and 2 molded rubber rings, ready for direct installation without additional parts. Critical precautions are as follows: 1) Keep all components ultra-clean, free of dirt, oil, or metal shavings, to prevent scratches on the sealing face; 2) Use a special installation tool to press the seal evenly into the housing—never hammer or apply uneven force; 3) Ensure the metal ring’s lapped sealing face is completely scratch-free before assembly; 4) Always replace both sides of the final drive as a pair to maintain rotational balance and prevent premature wear; 5) Verify the seal groove dimensions are within tolerance to avoid leakage.

Q: What is the operating temperature range, quality certification, and typical service life of this seal?
A: It operates reliably across a wide temperature range of -25°C to +120°C, covering cold winter construction in northern regions and hot summer operations in tropical areas. It meets Hyundai OEM quality standards, with 100% dimensional inspection, hardness testing, and pressure leakage testing performed before shipment. The warranty is 18 months or 2,500 working hours, whichever comes first. Under normal construction conditions, such as urban digging and loading, the service life averages 7,000–10,000 hours; in severe mud/water mining environments, it ranges from 4,000–6,000 hours.

Q: Can it directly replace the original Hyundai part, and is it compatible with older R-series models?
A: 100% direct OE replacement for the original Hyundai XKAH-00495 part. It is fully interchangeable with both older R-5 series (R55-5/R60-5/R80-5) and newer R-7/R-9 series models (R55-7/R60-7/R80-9). No modifications or additional parts are required for installation. However, we recommend inspecting the final drive housing for wear, corrosion, or damage before installation to ensure a tight seal and prevent oil leakage.
