Ball Bearing 6302

The accuracy of the bearing refers to the tolerance range of the bearing. The higher the accuracy, the smaller the tolerance range. Bearing accuracy is divided into P0/P6/P5/P4/P2, where P0 accuracy is the conventional accuracy level, which will not be displayed after the general model, and the smaller the number after the remaining accuracy P letter, the higher the accuracy level, and the tolerance value smaller. The precision grades selected for conventional motor bearings are P5 and P4 grades.

Bearing clearance is divided into radial clearance and axial clearance. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a certain axial load.

The numerical value of the conventional clearance is C0, the larger the clearance, the greater the shaking of the bearing, and the noise generated during operation will be larger than the conventional standard clearance. The clearance value selected for conventional motor bearings is C0 clearance.

Throughout today's market, there are a wide variety of low noise bearings. Before choosing, we should first understand their brands and characteristics. In general, Kent starts with the control of raw materials and uses GCR15, which is more wear-resistant, and has a longer service life. The produced bearings conform to the national ZV4 quality level and reach the P5 and P6 precision levels. As we all know, the higher the bearing accuracy, the smaller the error, in order to achieve the purpose of strong consistency and stable operation. Implement a full inspection of the noise level to ensure that the decibel value of miniature bearings is less than 23 decibels, the decibel value of miniature and small bearings is less than 25 decibels, and the decibel value of small bearings is less than 27 decibels, which is far lower than that of peers.
