Oil seal rubber is a kind of sealing component made from rubber materials, primarily used in mechanical equipment, especially in parts that need to prevent liquid or gas leaks. With its unique elasticity and sealing properties, oil seal rubber forms an effective sealing barrier between the shaft and the hole or other mating surfaces that need sealing. Oil seal rubber typically consists of a rubber body (also known as a sealing lip) and other auxiliary components (such as a metal skeleton or spring). In modern industry and daily life, oil seal rubber is an indispensable component. These seemingly ordinary small parts play a crucial role in various fields, bringing countless conveniences to our lives and can be regarded as: "Industrial wisdom behind the miracle of elasticity."
Oil seal rubber is a high polymer material with significant stretchability and excellent elasticity. Their most notable feature is a small elastic modulus and a high elongation rate. This characteristic allows oil seal rubber to maintain good sealing performance under various pressures and deformations, effectively preventing leaks of liquids, gases, or other substances. Oil seal rubber not only possesses air permeability resistance, preventing gas or liquid seepage but also withstand the erosion of various chemical media. Additionally, they exhibit good electrical insulation properties, ensuring the safe operation of electrical equipment.
There are many types of oil seal rubber, categorized in various ways. According to the source and method of raw materials, an oil seal rubber can be divided into natural rubber and synthetic rubber; based on appearance, they can be classified into solid rubber, emulsion rubber, liquid rubber, powdered rubber, etc.; by performance and application, besides natural rubber, they can be divided into general-purpose synthetic rubber, semi-general synthetic rubber, special-purpose synthetic rubber, and special synthetic rubber. Based on their structure and application, oil seal rubber can be divided into different types, such as TC oil seal and TA oil seal. Furthermore, they can be classified according to the chemical structure, type of filling materials, purpose, rubber type, and cross-linking form.
Oil seal rubber is widely used in numerous fields, including automotive, machinery, chemical, electronics, and medical industries. In the automotive industry, automotive oil seals are used in key components such as engines, transmissions, and brake systems to ensure the vehicle's normal operation and performance; in machinery manufacturing, oil seal rubber is used in bearings, gearboxes, and hydraulic systems, providing reliable sealing and shock absorption effects; in the chemical and electronics industries, oil seal rubber prevents the leakage of corrosive media, protecting equipment and components from damage.
