We believe that the tapered angle of the floating oil seal is small, which reduces the jump of the floating seal ring engagement ring caused by the external impact of the roller, improves the axial force of the seal engagement surface and keeps its axial force independent of the system shaft. It is beneficial to make the gap larger and change sharply. However, the sealing cone angle becomes smaller, it is easy to cause the rubber ring to skew on the cone surface when the roller is assembled, and the compression amount of the sealing seat on the rubber ring is increased, it is more difficult to ensure the correct position of the sealing engagement blade in the assembly. Analysis of the relevant data of some advanced companies in the world shows that the oblique angle of the cone surface of the floating oil seal becomes smaller, which is a development trend in design.
