Classification of rubber seals

Rubber seals are very common in modern industrial machinery production environments, and there are many ways to classify them. The following will introduce classification based on movement forms, materials and characteristics.

1. Classification by exercise form:

It can be divided into dynamic sealing and static sealing. A static seal usually refers to a seal between two static surfaces. Static sealing methods mainly use various forms of gaskets and packings. Dynamic seals can be divided into non-contact seals and contact seals, depending on whether the sealing ring is in contact with parts at relative speeds. Silicone seals are contact seals, and common movement methods include rotating shaft lip seals, repeated movement seals, etc.

2. Classification by material:

According to material classification, sealing rings are usually classified into different rubbers, such as nitrile sealing rings, fluororubber sealing rings, silicone rubber sealing rings, etc. This classification method mainly emphasizes the main material of the sealing ring.

3. Classification according to the characteristics of sealing rings:

According to the material type, usage conditions and other factors of the sealing ring, it can be divided into the following four categories: high-pressure-resistant sealing ring, high-temperature-resistant sealing ring, wear-resistant sealing ring, and corrosion-resistant sealing ring.
