A rubber sealing ring is an annular cover composed of one or several parts, fixed on one ring or gasket of a bearing and in contact with another ring or gasket or forming a narrow labyrinth gap to prevent lubricating oil leakage and foreign object intrusion.Features and materials:

Used for installation on various mechanical equipment, to provide sealing effect in static or moving states under specified temperature and pressure, as well as different liquids and gases

Material analysis of rubber sealing ring

(1) Fluororubber: It has high temperature resistance and can be used in environments ranging from -30 ℃ to+250 ℃. It is resistant to strong oxidants, oil, and acid and alkali. Usually used in high temperature, high vacuum, and high pressure environments, suitable for oil environments. Due to its various properties, fluororubber is widely used in industries such as petroleum, chemical, aviation, and aerospace.

(2) Silicone rubber: It has outstanding high and low temperature resistance, maintains good elasticity in the temperature range of -70 ℃ -+260 ℃, and has advantages such as ozone resistance and weather aging resistance. It is suitable as a sealing gasket in thermal machinery. Can produce insulation, insulation products, and rubber products.

3. Nitrile rubber: It has excellent resistance to oil and aromatic solvents, but is not resistant to media such as ketones, esters, and chlorides. Therefore, nitrile rubber is mainly used for oil resistant sealing products.

4. Chloroprene rubber: It has good resistance to oil, solvents, chemical media and other properties, but is not resistant to aromatic oils. Its characteristic is resistance to weather aging and ozone aging. In production, chloroprene rubber is commonly used to make door and window sealing strips, membranes, and general vacuum sealing products;

5. Ethylene propylene diene monomer (EPDM): It has the properties of temperature resistance, weather aging resistance, and ozone aging resistance, and is widely used in door and window sealing strips and the automotive industry.

6. Polytetrafluoroethylene composite gasket is a new type of sealing material made by combining polytetrafluoroethylene and synthetic rubber using a special production process. It combines the excellent characteristics of polytetrafluoroethylene and rubber, making the product have excellent corrosion resistance, high temperature resistance, elasticity, and sealing properties.
