A wheel hub oil seal, also known as a bearing seal, is a critical sealing device located between the wheel hub and the brake drum or disc. Its primary function is to prevent the ingress of dirt, water, and other contaminants into the wheel bearing while retaining the lubricating oil inside. This dual-purpose operation is crucial for maintaining optimal performance and preventing premature wear and tear. Proper installation and maintenance of shaft oil seals are essential to ensure their effectiveness. The seal should be inspected regularly for signs of wear and tear, such as cracks or damage to the lip. If any issues are detected, the seal should be replaced immediately to prevent leaks and damage to the system. Replacing a power steering oil seal is a relatively straightforward process for a trained technician
Despite its many advantages, skeleton oil sealing is not without its challenges. Over time, seals can degrade due to age, heat, or chemical exposure, necessitating regular inspections and replacements. Furthermore, improper installation or mismatched components can lead to premature failure of the seal, highlighting the importance of skilled technicians and quality control measures in the manufacturing process.
