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.
The materials used in manufacturing hydraulic seals are also vital to their performance. Common materials include rubber compounds, polyurethane, and PTFE (Polytetrafluoroethylene). Each material offers different advantages and is selected based on the operating environment. For example, PTFE seals are highly resistant to chemicals and extreme temperatures, making them ideal for demanding applications.

2. Crack Control Concrete is prone to cracking due to shrinkage, temperature changes, or excessive loads. Welded wire mesh helps to mitigate these issues by providing tensile strength that counteracts the tensile forces acting on the concrete. By incorporating wire mesh, builders can effectively control cracks, preserving the aesthetic and structural integrity of the concrete.
