1. Leak Prevention One of the primary functions of a hub oil seal is to prevent oil leaks. If the oil seal fails, the lubricant can escape, leading to insufficient lubrication of the bearings and other critical components. This can result in increased wear and tear, decreased performance, and eventually, catastrophic failure.
From an ecological perspective, seal dust plays a crucial role in nutrient cycling within marine environments. The organic matter released into the ecosystem can serve as a food source for various microorganisms, subsequently supporting the entire food web. Phytoplankton, the primary producers of marine environments, benefit from the nutrients in seal dust, which can enhance their growth and, in turn, bolster the populations of herbivorous marine organisms.

The applications of anti-crash bollards are diverse, extending beyond mere traffic control. In high-risk areas, such as the entrances of embassies or crowded marketplaces, these bollards act as a physical deterrent against potential terrorist attacks involving vehicles. By strategically placing them, urban planners can mitigate risks and protect their citizens from acts of violence. For instance, during public events where large crowds gather, temporary anti-crash bollards can be deployed to create secure perimeters and allow law enforcement to monitor the area more effectively.
