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.



2. Contaminant Protection Grease seals act as a first line of defense against contaminants. Dust, water, and debris can enter the bearing assembly and potentially lead to corrosion, pitting, and other forms of wear. By keeping these contaminants out, grease seals help maintain the integrity of the bearings.

The operation of a pressure regulator is largely based on the principle of balance between the inlet pressure, outlet pressure, and the spring tension within the device. As the high-pressure fluid enters the regulator, it acts against a diaphragm, which moves in response to changes in pressure. When the output pressure rises above the predetermined level, this movement causes a valve to close, restricting the flow. Conversely, if the output pressure drops, the valve opens, allowing more fluid to flow through. This feedback mechanism ensures that the output pressure remains steady, regardless of fluctuations in the input.
