The primary function of an oil seal for a rotating shaft is to retain the lubricating oil within the system and prevent it from leaking out. This is important for maintaining proper lubrication of the bearings and moving parts, which helps to reduce friction and wear, and prolong the life of the equipment. Without a properly functioning oil seal, oil leakage can lead to equipment failure, costly repairs, and downtime

Moreover, the oil seal acts as a barrier against external elements like dust, water, and road debris. These substances can cause corrosion, wear, and even damage to the sensitive components inside the hub, potentially causing significant performance issues or even complete breakdowns These substances can cause corrosion, wear, and even damage to the sensitive components inside the hub, potentially causing significant performance issues or even complete breakdowns

The material selection for oil seals is crucial as it determines their performance, durability, and compatibility with various fluids. Common materials used in oil seals include nitrile rubber, fluoroelastomers, silicone rubber, and polytetrafluoroethylene (PTFE). Nitrile rubber is widely used due to its good chemical resistance, oil resistance, and moderate temperature range Nitrile rubber is widely used due to its good chemical resistance, oil resistance, and moderate temperature range
