5. FAQ

Q: Why is 100CR6 steel selected for the metal rings, and what are the advantages of NBR60 rubber here?
A: 100CR6 is a high-carbon chromium bearing steel with exceptional hardness, wear resistance, and dimensional stability under heavy loads, high torque, and temperature fluctuations—critical for long-term reliable rotation in the final drive. NBR60 is a premium nitrile rubber compound offering excellent oil resistance, good low-temperature flexibility (-25°C), and balanced hardness to ensure uniform sealing pressure without excessive friction or wear. It also resists aging and ozone degradation, maintaining elasticity even after thousands of hours in harsh construction environments.

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 use. We also offer three upgraded alternatives: brown high-temperature NBR70 for desert or summer high-heat regions (up to 130°C), green chemical-resistant HNBR for waste treatment plants or sites with hydraulic fluid contamination, and cast iron metal rings for heavy mining applications requiring higher impact resistance. The standard design features a square rubber cross-section; low-friction PTFE-coated metal rings are available for high-speed travel motor applications.

Q: What does this assembly include, and what are the critical installation steps and precautions?
A: It’s 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: 1) Keep all components ultra-clean (no dirt, oil, or metal shavings) to prevent seal face scratches; 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 before shipment. The warranty is 18 months or 2,500 working hours (whichever comes first). Under normal construction conditions (urban digging, 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-00372 part. It is fully interchangeable with both older R-5 series (R55-5/R60-5/R80-5/R110-5) and newer R-7/R-9 series models (R55-7/R60-7/R80-9/R110-7). No modifications or additional parts are needed 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.
