Rubber oil seals are essential sealing components widely used in mechanical equipment. They primarily prevent the leakage of lubricating oil and the intrusion of external dust, moisture, and debris, thereby protecting the normal operation of the equipment. Their core structure includes sealing lips, reinforced skeletons, and springs. The sealing lips achieve sealing by tightly contacting the rotating shaft, the reinforced skeleton provides support and structural stability, and the springs enhance the elasticity and adherence of the sealing lips.

Rubber oil seals exhibit excellent sealing performance, wear resistance, and high-temperature resistance, enabling stable operation under high pressure, high speed, and harsh environments. Depending on the application requirements, they can be manufactured from different materials. For instance, fluororubber is suitable for high-temperature and chemically corrosive environments, silicone rubber adapts to low-temperature and anti-aging scenarios, and nitrile rubber demonstrates outstanding oil resistance. Moreover, they are easy to install, have a long service life, and significantly reduce equipment maintenance costs.

Rubber oil seals are extensively applied in automotive engines, industrial machinery, and hydraulic systems. They can also be designed with double-lip structures to simultaneously prevent internal and external leakage. Their flexible design and superior performance make them a vital solution for enhancing equipment reliability and sealing efficiency in modern industries.
