Floating oil seal requirements for the surface

Floating oil seal requirements for the surface

Alice 2019-10-11 10:01:24
The floating seal ring is a workpiece with high precision. When using it, it is necessary to extend the service life of the original as much as possible. If the replacement is made in the middle, it is easy to cause problems such as improper matching and affect the use. So what are the requirements for the surface of the seal ring with a floating oil seal? Firstly, the floating oil seal has higher requirements on the surface hardness of the floating seal ring. When it is made, the higher hardness can improve the wear resistance. In order to make the surface reach higher hardness, the whole quench hardening treatment is required, but the quench hardening is required. Will cause the metal ring to deform. In addition, there are various surface hardening treatments such as nitriding and laser quenching, and these methods can reduce the amount of deformation of the metal ring as compared with the overall quenching. If the surface roughness of the floating oil seal is large, the wear degree will increase and the wear resistance will be weakened.
