Hebei Hankai high pressure oil seal

The nomenclature 30x42x7 describes the oil seal's three critical dimensions the inner diameter (ID), outer diameter (OD), and width (W). Specifically, this oil seal features an inner diameter of 30 mm, an outer diameter of 42 mm, and a width of 7 mm. These measurements indicate that it is designed to fit into a specific space within a machine, preventing the leakage of fluids, particularly oil, from critical components like shafts and housings.

Conclusion

1. Preventing Fluid Leakage One of the primary functions of wheel oil seals is to prevent lubricant loss. When oil leaks from the system, it can lead to reduced lubrication, increasing wear and tear on components and possibly resulting in severe mechanical failures.
