[0002] Bearings are parts that support the "axle" that rotates in a machine. Machines that use bearings include cars, airplanes, generators, etc. Bearings are also used in household appliances such as refrigerators, vacuum cleaners, and air conditioners that we commonly use in our lives. In these machines, bearings are responsible for providing support for the "axle" on which parts such as wheels, gears, turbines, and rotors are installed, helping the shaft to rotate smoothly. Since many rotating shafts are used in various machines, bearings have become an indispensable part.

[0003] The bearing can be directly or indirectly connected to the connecting shaft of the application equipment. During the operation of the bearing, it may move along the connecting shaft. The reason for this may be that the matching accuracy of the two is not high during the design, or it may be caused by wear due to long-term use. The movement of the bearing will more or less affect the stability and safety of the application device. Therefore, the utility model proposes a roller bearing. Utility Model Content
