As an authorized ISUZU distributor, we offer the WHEEL HUB INNER OIL SEAL (Part No. 8-94336316-1), a crucial seal for 4HK1 excavator engines. It prevents lubricant leakage, blocks dust and moisture, and ensures bearing stability. Factory-calibrated, it fits multiple ISUZU excavator models (NKR, NLR, etc.) without modification, addressing seal-related bearing wear and oil consumption. Ideal for complex worksites, it's essential for maintaining engine transmission performance.

We strictly follow ISUZU original factory standards for quality control. The wheel hub inner oil seal, made of high oil-resistant nitrile rubber with a reinforced metal skeleton, has passed -40℃ to 120℃ extreme temperature, 1000-hour oil immersion, and high-frequency vibration sealing tests. This ensures excellent sealing under harsh conditions, with reduced risk of aging, deformation, and cracking. Manufactured in line with ISO 9001, each seal is tested for dimensional accuracy and randomly checked for sealing performance, meeting ISUZU's quality standards. This extends excavator engine life and cuts maintenance costs.
