Oil seals are the customary name for general seals. As the name implies, oil seals are mechanical components used to seal oil (oil is the most common liquid substance in the transmission system and also refers to general liquid substances). Oil seals are a basic concept of mechanical seals.
The oil seal is also called the rotary shaft lip seal. The mechanical friction portion uses oil seals to prevent oil from leaking from the mechanical gap due to oil ingress during mechanical movement. However, with the development of mechanical technology, in addition to oil, it is necessary to prevent leakage of water and chemical liquid and dust from the outside with earth bricks. In this case, an oil seal is also used.
From the sealing function, characteristics, structure type, working state and sealing mechanism of the oil seal, it can be divided into various forms and different names, but it is customary to generally rotate the shaft lip seals called oil seals, static seals and dynamic seals (general reciprocating motion). Seals are called seals. It is generally not very meaningful to dialectify the definition of a seal. More attention is paid to the practical application of oil seals and to the role played by leaks in seals.
Standard oil seal: The standard oil seal is a representative oil seal selected according to NOK's years of performance and user requirements in the world market.
General oil seal: The general oil seal is an oil seal other than the standard oil seal. It is an oil seal designed according to specific machinery and special conditions and special requirements.
The oil seal cover is also called the end cover or the oil cover. It is mostly used in gearboxes and gearboxes and gearboxes to prevent dust and dirt from entering the moving parts and causing damage.
