Floating seal ring is a high precision requirements of the workpiece, the use of the time required to extend the life of the original, if the middle of the pieces, easy to cause the match is not appropriate and many other issues affecting the use. So what does the floating seal have on the surface of the seal ring?
      First, the hardness of the surface of the floating ring ring is relatively high, at the time of production, higher hardness can improve the wear resistance of the performance, in order to achieve a higher hardness of the surface, the need for the overall quenching and hardening treatment, but quenching hardening Metal bad deformation. In addition, there are nitriding, laser quenching and other surface hardening treatment, these methods compared with the overall quenching, can reduce the amount of metal ring deformation.
If the surface roughness of the floating ring is large, it will cause increased wear and wear resistance. In the boundary lubrication conditions, to have enough space to store lubricants, play a role in reducing friction, can extend the life of life
