Proper Assembly and Storage of Oil Seals: Essential Steps and Precautions for Optimal Performance

June 21, 2023

The following are the precautions to be taken during the transportation and storage of oil seals:

  1. Do not open the original packaging: Oil seals are precision components, and to avoid contamination and damage from the external environment, do not open the original packaging. Try to keep the oil seals in their original packaging until assembly.
  2. Avoid direct sunlight and high-temperature sources: Oil seals should be protected from direct sunlight and should not be placed near high-temperature sources as it can accelerate rubber aging.
  3. Dust and dirt protection: Oil seals should not be left exposed or scattered. Ensure that the oil seals are kept in a closed or covered state to prevent dust and contaminants from entering.
  4. Avoid excessive impact: During transportation and use of oil seals, avoid excessive impact to prevent deformation and spring detachment, ensuring their integrity.
  5. Avoid tying or hanging on nails: Oil seals should not be tied with ropes or hung on nails or metal wires as this can damage the sealing lips and affect their sealing effectiveness.
  6. Avoid damp environments: Oil seals should not be placed in damp areas to prevent rusting of metal components and to maintain their performance and lifespan.
  7. Keep away from TVs and ozone-generating sources: Avoid placing oil seals near TVs or devices that produce ozone, as the electromagnetic field from the TV and ozone can adversely affect the oil seal material.
  8. Avoid friction on the lip end: Do not rub the lip end of the oil seal with fingernails or hard objects to prevent damage to the sealing lips and maintain their sealing performance.

The assembly steps and precautions for oil seals are as follows:

  1. Use of lubricants: When installing the oil seal, apply an appropriate amount of lubricant to the outer surface to reduce friction and wear. The lip portion should be coated with suitable clean lubricating grease. For oil seals with dust lips, fill the space between the main lip and the dust lip with clean lubricating grease before assembly.
  2. Correct assembly orientation: Install the oil seal with the sealing lip end facing the side where the sealing medium is required, and avoid reverse assembly to ensure proper functioning of the oil seal.
  3. Use of specialized tools: When inserting the oil seal into the seat hole, use specialized tools to push it in and prevent misalignment.
  4. Prevent lip edge damage: Take various measures to prevent damage to the lip edge of the oil seal during threading, keyway, spline, etc., and use specialized tools for assembly to ensure the integrity of the lip edge.
  5. Apply even pressure: When installing the oil seal, place it horizontally into the seat hole and apply even pressure. Avoid tilting or using excessive force to prevent damage to the oil seal.

Proper assembly and storage of oil seals are crucial to ensure their performance. Improper assembly or storage can lead to seal failure, oil leakage, or damage, which can affect the equipment's performance and reliability. Therefore, it is important to follow the correct steps and precautions during the assembly and storage of oil seals.
