In addition to preventing leaks, the outer hub oil seal also helps to keep dirt and water out of the wheel hub. If these contaminants were to enter the hub, they could mix with the lubricant and create a sludgy, abrasive mixture that can damage the bearings and other components. By creating a barrier between the outside environment and the lubricant inside the hub, the oil seal helps to ensure smooth and efficient wheel operation.
Another critical aspect of oil seals is their ability to prevent the ingress of contaminants such as dust, dirt, and water.

45x62x8 oil seal. By keeping these contaminants out, oil seals help to extend the life of the machine and ensure optimal performance.


In addition to their durability and versatility, PU oil seals offer superior sealing performance. They effectively prevent oil leakage and contamination, ensuring the smooth operation of machinery and reducing the risk of costly repairs. The material also has low friction properties, which helps to minimize wear and tear on moving parts

One of the main signs that a wheel hub seal needs to be replaced is the presence of grease around the wheel hub. If you notice grease leaking from the wheel hub area, it is likely that the seal is worn out and needs to be replaced. Another common indication that the wheel hub seal is damaged is the presence of a grinding or squeaking noise when driving

wheel hub seal. This noise is caused by the lack of lubrication in the wheel hub, which can lead to metal-on-metal contact and damage.
