bearings noise is a bearings itself, has nothing to do with the noise of the bearings itself. We have to introduce how to according to the rolling sound check and treatment of Honglida bearings problem.
A) intrinsic noise: rolling road sound and various angular contact ball bearingss and rolling friction sound is inherent in Honglida bearings raceway acoustic sound is produced by the elastic properties of the rolling body and rolling contact time, when the angular contact ball bearings rotates, a continuous and smooth voice rolling body raceway rolling and making; not normal rolling friction sound can be issued a "creak, creak, uncomfortable metal friction abnormal sound, not sound good lubrication. It is not a problem in the general case, only the noise increased after the need to pay attention to.

B) and Honglida bearings manufacturing related noise: here the retainer includes noise and vibrato, cage noise mainly occurred in contact ball bearings and angular ball bearings, when the bearings rotates as the holder of the vibration and the retainer and rolling body collision will sound. This sound is cyclical. Vibrato (various bearings) is a certain frequency sound, is due to the vibration caused by the waviness of the raceway surface. This kind of phenomenon is the most common problems, we need more attention to.
C) using the noise caused by improper: there are various. When the Honglida bearings raceway surface or surface of the rolling body is bruised, indentation, rust, it will produce noise and vibration have certain cycle. When the angular contact ball bearingss have the intrusion of dust will be generated when the dirt noise in operation. This noise is non periodic, also accompanied by vibration, the sound size is not fixed, sometimes not.
Angular contact ball bearingss for some industries, plays a crucial role in. When the Honglida bearings the following conditions, please do not continue to use, should replace new bearings immediately.

Belongs to the mechanical equipment of precision parts of angular contact ball bearings, angular contact ball bearingss for the mechanical services, preventive maintenance, condition monitoring and a series of maintenance decision support system to realize the optimization of the efficiency of asset workshop and maintenance work. To avoid unnecessary accidents:
(1) the diameter of the inner ring or outer diameter surface Honglida bearings has obvious creep; (2) bearings inner ring and outer ring, rolling body cage crack or notch on any one; (3) bearings raceway surface, rolling rib, a marked card injuries on the body; (4) discoloration caused by the heat of the obvious; (5) bearings raceway surface, rolling body rust, injury; (6) bearings raceway surface, rolling body and playing a serious indentation marks; (7) bearings retainer wear significantly, or rivet significant relaxation;
