tcn oil seal
The hub axle seal's primary function is to keep the axle lubricated. The lubricant, often a type of grease or oil, is crucial for reducing friction between moving parts. Without proper lubrication, the components can suffer from overheating and excessive wear, potentially leading to significant damage and costly repairs. Additionally, the seal prevents water and dirt from entering the axle assembly, which can cause rust and corrosion, further jeopardizing the integrity of the axle.


4. Natural Aging Even new shingles are not immune to the effects of aging. As asphalt shingles endure seasonal changes, the granules on their surface can gradually erode or loosen due to thermal expansion and contraction. Exposure to sunlight, rain, and temperature fluctuations can all contribute to this natural degradation process.
