[0002] Bearings are one of the important components in mechanical systems. Their main function is to support rotating shafts or linear motion shafts, reduce friction and wear during movement, and ensure the normal operation of mechanical equipment. Cylindrical roller bearings, as a common type of bearing, have advantages such as high load-bearing capacity, simple structure, and convenient installation, and are widely used in various mechanical equipment.
[0003] Based on the above, most cylindrical roller bearings currently generate noise during operation due to friction and collision between the rolling elements and the inner and outer rings, as well as vibration of the cage. Being in a high-noise environment for a long time will not only affect the normal operation of the equipment, but also have adverse effects on the human body. Summary of the Invention
[0004] In view of this, the present invention provides a low-noise cylindrical roller bearing, which has an outer ring, a retaining ring, cylindrical rollers, a limiting ring, a supporting inner ring, and a limiting inner ring, thereby solving the problem that most cylindrical roller bearings generate a certain amount of noise during operation due to friction and collision between the rolling elements and the inner and outer rings, as well as vibration of the cage. Long-term exposure to a high-noise environment not only affects the normal operation of equipment but also has adverse effects on human health.
