Processing methods and techniques for deep groove ball bearing parts

Deep groove ball bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element, and cage. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings. Although there are many types of rolling bearings, their structural types, tolerance grades, material selection, and processing methods are different.

Reasons for damage to deep groove ball bearings

Deep groove ball bearings are precision parts, and only some of them are damaged in actual applications. Most of the reasons for bearing failure are many - loads exceeding the original estimate, ineffective seals, too small bearing clearance caused by too tight fit, etc. Any of these factors has its own special damage type and will leave special damage marks. Therefore, by examining the damaged shaft bearings, the possible causes can be found in most cases. Generally speaking, one-third of the shafts are damaged.

Causes and countermeasures of excessive temperature of deep groove ball bearings

Generally, if deep groove ball bearings are used correctly, they can be used to their maximum lifespan. If they are not used correctly, they may be damaged prematurely. This early damage, which is relative to fatigue life, is called the quality use limit of failure or accident. It is mostly caused by improper installation, use, and lubrication, or foreign matter intruding from the outside. The main reasons for the damage of deep groove ball bearings, such as the jamming of bearing rings and flanges, are insufficient lubricant, unsuitable,

Deep groove ball bearing assembly standards and methods

(1) Technical requirements for deep groove ball bearing assembly ① The end face of the deep groove ball bearing marked with the code should be installed in a visible direction to facilitate checking when replacing. ② The arc radius at the step of the journal or housing hole should be smaller than the arc radius at the corresponding position on the bearing. ③ After the bearing is assembled on the shaft and in the housing hole, there should be no skew. ④ Among the two coaxial bearings, one must produce axial movement when the shaft expands with heat. ⑤ When assembling deep groove ball bearings, dirt must be strictly prevented from entering the bearing.
