Hebei Hankai wheel bearing grease seal

Oil seals are specially designed sealing devices that fit into machinery to prevent the leakage of oil and other fluids while keeping contaminants like dust, dirt, and moisture out. Typically made from elastomeric materials, they exhibit flexibility, durability, and resistance to a wide range of temperatures and aggressive chemicals. Oil seals come in various shapes and sizes, tailored to fit specific applications and installation spaces.

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.

The 25% 2035 7 oil seal finds applications in various fields such as automotive, aerospace, industrial machinery, and even household appliances. In automotive engines, for example, oil seals are critical for preventing oil leaks, which can lead to engine failure. In industrial machinery, they are used to protect bearings and other moving parts from contamination, ensuring smooth and efficient operation.
