新闻概况: Oil seals are mainly used to seal oil seals in rotary motion. Most of the main oil seals are equipped with springs as the main source of seal contact pressure. Due to the metal spring's resistance, fatigue resistance (long-term use without stress attenuation), and its good adjustability (spring length adjustment), and because the oil seal lip is not directly installed in the groove like the "O" ring It is connected to the skeleton through a certain flexible waist, so that it has a certain adaptability (that is, the machining accuracy does not need to be as high as the "O" shape, allowing a certain degree of eccentricity). The new oil seal is widely used in general After continuous research, new oil seals with long life and high speed are also being developed.
