Performance requirements for floating oil seals

2021-05-24 10:50:49
Floating seal ring is a workpiece with high precision requirements. When using it, it is necessary to extend the service life of the original as much as possible. If the part is replaced in the middle, it is easy to cause inappropriate matching and affect use.

First of all, the surface hardness of the floating seal ring is relatively high. During production, higher hardness can improve the wear resistance. In order to achieve higher hardness on the surface, an overall quench hardening treatment is required, but quench hardening will cause The amount of deformation caused by metal damage.

If the surface roughness of the floating seal ring is large, the degree of wear will increase and the wear resistance will be weakened. Under the condition of boundary lubrication, there can be enough space to store lubricating oil, which can reduce friction and prolong the service life.
