Hebei Hankai 35 72 10 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.

The designation 25% 2035 7 refers to specific dimensions and material characteristics of the oil seal. In the mechanical context, the first number often represents a percentage of the sealing area, while the subsequent figures usually denote the size and type of the seal. The 25% indicates a high sealing efficiency, which is essential for maintaining a controlled environment and minimizing leakage. The numbers 2035 can denote dimensions such as inner and outer diameters or other relevant measurements, emphasizing the oil seal's suitability for particular machinery. Finally, “7” may refer to the design style or material hardness, providing insights into its durability and resistance to wear and tear.
