Sealed spherical roller bearings are a key component of mechanical equipment nowadays. Its key function is to support industrial equipment to rotate product workpieces, reduce the friction in the whole process of exercise and fitness, and ensure its rotation accuracy.
According to the different friction characteristics of sports and fitness electronic devices, sealed spherical roller bearings can be divided into two categories: flipping sealed spherical roller bearings and dragging sealed spherical roller bearings. Among them, flipping sealed spherical roller bearings has been standardized and integrated for a long time, but compared with dragging sealed spherical roller bearings, its shaft diameter specifications, vibration, and noise are very large, and the price is also high. Turning sealed spherical roller bearings generally consists of four parts: two sides, internal threads, a turning body, and ball sealed spherical roller bearings. According to the appearance of the turnover body, turnover-sealed spherical roller bearings can be divided into two categories: ball-sealed spherical roller bearings and roller-sealed spherical roller bearings.
