One of the key challenges in shaft oil seal design is to balance the competing demands of sealing effectiveness and shaft mobility. If the seal is too tight, it can impede the shaft's rotation, leading to increased friction and heat generation. On the other hand, if it is too loose, it may not be able to prevent oil leakage effectively On the other hand, if it is too loose, it may not be able to prevent oil leakage effectively

In addition to their functional benefits, oil hub seals also play a crucial role in environmental protection
oil hub seal. By preventing the leakage of oil and other hazardous substances into the environment, these seals help to minimize the impact of oil exploration and production on the natural world.

On the other hand, Lithopone B301 is a lower-grade pigment with a lower zinc sulfide content compared to B311. While B301 may not offer the same level of performance as B311, it is still a cost-effective option for applications where high opacity is not a priority
