1. Categorize by type of exercise

Usually there are two types of movement of oil seal seal, namely dynamic seal and static seal.Static seal refers to the seal on the two static surfaces of the sealing part of the equipment.The most widely used seal rings in seals are mainly used in static seals, followed by gasket seals.In dynamic seal, it can be divided into contact dynamic seal and non-contact dynamic seal according to whether the oil seal at the sealing part of the equipment is in contact with the parts that are in relative motion.Among them, we often use the oil seal for the contact seal.Usually in the dynamic seal, the common forms of oil seal are rotary shaft lip oil seal and reciprocating motion oil seal.

2. Categorize by material

Through different materials to divide different oil seals, the form of this classification is many, usually used more nitrile rubber oil seal, silicone rubber oil seal, fluorine rubber oil seal, etc..Other common materials are not listed at all.

3. Classify according to the characteristics of oil seals

This classification is mainly based on the characteristics of the oil seal, the use of the oil seal and the selection of materials to divide.It can be divided into high temperature resistant oil seal, low temperature resistant oil seal, high pressure resistant oil seal, wear resistant oil seal, corrosion resistant oil seal and so on.

The division of oil seal is generally the above several kinds, rich types of oil seal.There are a lot of models, in general, when choosing will be combined with their own actual needs for selection.
