Description
A deep groove ball bearing assembly with good dustproof effect Technical Field
[0001] The utility model belongs to the technical field of bearings and relates to a deep groove ball bearing assembly with good dustproof effect. Background Art
[0002] Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used type of rolling bearing. They are characterized by low friction and high rotational speeds. They can be used in components bearing radial loads or combined radial and axial loads, as well as axial loads. Examples include low-power electric motors, automobile and tractor transmissions, machine tool gearboxes, and general machinery and tools. The bearing housing is a supporting component of the bearing, used to control its position and facilitate assembly with other components. However, in actual applications, due to other factors, the bearing may need to be placed in an edge or corner, making conventional bearing housings inadequate or difficult to assemble. Furthermore, because corners are difficult to clean, impurities are more likely to accumulate in these areas than in other assembly locations, potentially entering the bearing housing, causing wear and shortening the bearing assembly's service life.
