Production process of floating oil seal

  • Author:Alice
  • Release on:2020-04-02
For floating oil seals, the production process is very important. Currently, there are mainly two types of raw materials commonly used in casting and forging.


The surface roughness of the floating seal ring in the floating oil seal has a great impact on the abrasion resistance. Such a roughness requirement is a standard that can be ground or polished. Pull back, after many researches, the fine structure can provide storage space for lubricating oil. Thus, a uniformly dispersed microporous structure is formed, which can adapt to higher line speeds.


In addition, for floating oil seals, the surface hardness requirements are very high. Therefore, in order to achieve such hardness and improve wear resistance, for most floating oil seals, quench hardening treatment or sealing surface hardening treatment is also required.
