The oil seal serves to prevent the lubricating oil in the bearing housing from leaking out
It prevents the lubricating oil in the bearing housing from splashing out axially, serving as a seal.
The main function of the oil seal is to prevent the engine oil inside the bearing housing from being flung out due to the high speed of rotation of the shaft. It also prevents cooling water from entering the bearing housing through the bearing end caps, which could cause the oil to emulsify. Unless there are specific requirements, rubber is generally used for this purpose!
