The floating sealing ring is a workpiece with high precision requirements. When used, the original service life needs to be extended. If it is an intermediate workpiece, it can easily cause many problems such as improper fit and affect the use. So what is the function of the sealing ring surface of the floating seal?
First of all, the surface hardness of the floating ring is relatively high. During production, higher hardness can improve the wear resistance. In order to achieve higher surface hardness, overall quenching and quenching treatment are required, but the quenching hardened metal deforms poorly. In addition, there are surface quenching treatments such as nitriding and laser quenching. These methods can reduce the deformation of the metal ring compared with overall quenching. If the surface roughness of the floating ring is large, it will cause wear and increase wear resistance. Under boundary lubrication conditions, there must be enough space to store lubricant, which can reduce friction and extend service life.
