It is not a single type of sealing component, but a combined design that integrates two or more different functional sealing elements. This design aims to provide a more comprehensive and reliable sealing effect than a single oil seal. Core structure and working principle A typical COMBI oil seal usually consists of the following two parts: Main seal (usually inward): Material: Usually, it is oil-resistant rubber (such as NBR nitrile butadiene rubber) or high-performance rubber (such as FKM fluororubber). Function: This is the core functional part of the oil seal. It is equipped with a compression spring, and its main function is to prevent the internal lubricating oil or grease from leaking out. It is responsible for sealing the oil. Secondary seal/dust lip (usually outward-facing): Material: It can be the same rubber, or it can be a more durable material. Function: This is an independent, springless sealing lip. Its main function is to prevent external dust, dirt, moisture, impurities, and other contaminants from entering the system interior. It is responsible for dust prevention. 12019673B COMBI SF 35*52*17/18.5 Oil Seal for 641734 CARRARO Why more and more customers choose Xingtai Honglei Seal Manufacturing Co., Ltd. (KDIK OIL SEAL)?
