  • OIL SEALS

  • In addition to their functional capabilities, hub oil seals also play a crucial role in extending the life of machinery. By preventing the loss of lubricant and the ingress of contaminants, these seals help to reduce wear and tear on moving parts, leading to longer equipment life and reduced maintenance costs.
  • Furthermore, the use of rubber offers chemical and weather resistance advantages
  • Improper Installation: Incorrect oil seal fitting can cause immediate or premature failure. This improper fit can be due to many reasons, such as damage during installation, misalignment, or using the incorrect size.
  • Under the action of the skeleton oil seal, the rigidity of the oil film just makes the oil film and the air contact end form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft. The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak; if the thickness is too small, dry friction may occur, causing the oil seal and shaft to wear; if there is no oil film between the sealing lip and the shaft, it is easy to cause heat and wear. . Therefore, when installing, it is necessary to apply some oil on the sealing ring, and at the same time ensure that the skeleton oil seal is perpendicular to the axis line. If it is not perpendicular, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive sealing of the lip. wear. During operation, the lubricant in the casing seeps out a little, so that it is ideal to form an oil film on the sealing surface.

  • Similar to the SM but with additional dust lip. Application are the same as type SGT , when the requested type is not available.
  • Moreover, a faulty valve cover gasket can also cause oil to mix with coolant, leading to a condition known as mayonnaise in the coolant, which is a clear indication of a problem
  • An oil seal, primarily constructed from rubber, is a vital sealing device designed to prevent the ingress of contaminants and the egress of lubricants or other fluids. The rubber material, chosen for its unique properties, forms the core of this seal, providing a flexible barrier that adapts to various surfaces and withstands harsh conditions.
