Description

VK cap oil seal, also known as end cap oil seal, is a rubber and metal composition, used for lubricating oil, water, glaze and other media sealing.

1. Structure and Composition

Skeleton:

  • Metal Skeleton: The skeleton of VK type oil seal is usually made of metal material, such as steel or iron. This metal skeleton provides structural support and enhances the durability and strength of the seal, ensuring that it maintains a stable shape during operation.
  • End Cap Construction: The skeleton is designed in the form of an end cap or bonnet, which usually covers the outer edge of the seal.

Seal lip:

  • Material: The sealing lip is usually made of elastic material, such as rubber, Viton, etc. It is in direct contact with the rotating shaft or other moving parts to form a sealing effect.
  • Design: The single lip design makes it simple and efficient for applications requiring a basic seal. The sealing lip can be designed in different shapes to suit various sealing needs.

End caps or caps:

  • Structure: The end cap portion of the oil seal usually covers the outside of the sealing lip, which serves to protect the sealing lip and at the same time enhances the overall structural strength of the oil seal.
  • Function: The end cap design not only improves the mechanical strength of the seal, but also prevents external contaminants, such as dust and dirt, from coming into direct contact with the seal lip.

2. Feature

End cap design:

  • Protection: The design of the end cap or cap protects the sealing lip, prolongs the service life of the oil seal and prevents external contaminants from affecting the sealing performance.
  • Enhanced structure: The metal skeleton and end cap design enhances the structural strength of the oil seal, making it perform better under high pressure and harsh environment.

Sealing Performance:

  • EFFECTIVE SEALING: Despite the single-lip design, proper materials and manufacturing processes ensure that good sealing performance is provided.
  • Protective: The additional protection of the end caps makes Type VK oil seals superior in preventing contamination.
  • Wide range of applications: VK type Simmerring oil seals can be used in a variety of mechanical equipment and automotive components, especially those with high sealing requirements or in harsh working environments.

3. Application Scene

  • Automotive industry: used in engine, transmission, differential and other components to prevent lubricant leakage and protect sealing lips from contaminants.
  • Industrial equipment: such as pumps, compressors, reducers, etc., for mechanical equipment that requires reliable sealing protection.
  • Mechanical equipment: widely used in a variety of mechanical equipment, especially in the more severe working environment, such as high temperature, high pressure or pollutants.
