SG type skeleton single lip with groove oil seal

SG type skeleton oil seal, also known as single lip with groove oil seal, is a kind of mechanical sealing element with special structure, which is often used to prevent lubricant or liquid leakage, and at the same time, prevent external pollutants from entering the inside of the equipment.

Description

SG type single lip oil seal, peripheral oil groove design, internal full package, single main lip oil seal with spring inside. It belongs to rotary oil seal, which is used for sealing in oiled, and dust-free occasions, withstanding pressure of 0.03MPa, within 0.3kgf/m2. According to the different use of media, pressure and temperature, choose a different material. Common materials include: butyl rubber SG type skeleton oil seal, fluorine rubber SG type skeleton oil seal, silicone rubber SG type skeleton oil seal and so on. They are mainly used in various industrial seals such as motor oil seals, reducer oil seals, gear box oil seals, motor oil seals, mechanical arm oil seals, wind power generation and so on.

  1. Main Components

    • Skeleton: made of metal material (such as steel or iron) to provide structural support and maintain the stability and durability of the oil seal.
    • Seal lip: usually made of elastic material (e.g. rubber, Viton, etc.), the seal lip contacts with the shaft during the operation of the equipment to form a sealing effect.
    • Grooves: The sealing lip is provided with one or more grooves that are designed to hold lubricating oil or liquid to make the seal more effective.
    • Spring: The built-in spring (usually made of stainless steel) exerts a certain pressure to make the sealing lip close to the shaft, thus improving the sealing effect.
  2. Features

    • Single-lip design: SG type oil seal adopts single-lip design with simple structure, which is suitable for various scenarios requiring basic sealing.
    • Design with grooves: The sealing lip is equipped with grooves, these grooves can effectively capture and hold the lubricant and enhance the sealing performance, especially under high temperature or high speed operation.
    • Skeleton Reinforcement: The metal skeleton provides additional strength and stability, enabling the oil seal to withstand higher operating pressures and temperatures.
  3. Application Scenarios

    • Automotive industry: used in engine, transmission, steering system and other components to prevent lubricant leakage and external contaminants from entering.
    • Industrial equipment: such as pumps, compressors, reducers, etc., especially in application scenarios that require high sealing performance.
    • Mechanical equipment: widely used in a variety of mechanical equipment, especially where sealing reliability needs to be improved.
