Prevent Bearing Cage Noise Measures Solution

When the bearing is rotating, the free vibration of the cage and its impact with the rolling element or the ring will cause noise.
There are many reasons for its noise, so we should pay attention to it when it is installed to avoid noise during use

Because the cage hole clearance of bearings and the cage and ring clearance inevitably exist in the bearing product, it is very difficult to completely eliminate the cage noise, but it can be improved by reducing the assembly error, optimizing the reasonable clearance and cage cross-flow momentum.

Another cage special sound is the noise caused by the self-excited vibration of the cage caused by the friction between the cage and the guide surface of other bearing parts. The stamping cage of the imported bearing is thin, the bending stiffness in the radial and axial plane is low, the overall stability is poor, and the bearing will produce self-excited vibration due to bending deformation when it is rotating at high speed, causing noise.

The most common is the bearing due to improper lubricants and dust into the noise.
If the bearing is caused by improper lubricant noise, do not worry too much, because this problem can be effectively solved, its methods include the following three:

Choose the right lubricant;

Add lubricant according to the specified lubrication amount;

Replace the lubricant regularly to avoid hardening of the lubricant.

If the bearing surface is damaged and dust enters, there is no need to worry, because there are corresponding solutions. Here's how

First of all, it is necessary to remove the bearing for inspection and record its appearance. At the same time, it is necessary to determine the amount of remaining lubricant in the bearing and sample it before cleaning the bearing.

Cleaning can be divided into two steps of rough washing and fine washing, usually using neutral and water-free diesel or kerosene as a cleaning agent, and often filtered to keep clean. After cleaning, anti-rust oil or anti-rust grease should be coated on the bearing surface immediately to avoid oxidative corrosion.

Inspection and judgment

In order to determine whether the removed imported bearing can be used again, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance, as well as the mating surface, raceway surface, cage and seal ring. The inspection results can be evaluated by personnel who are familiar with bearings or proficient in bearing knowledge. The criteria may vary depending on mechanical properties, importance and inspection cycle.

If the following damage occurs, the rolling bearing must be replaced and cannot be reused:

Bearing parts are broken and defective.

The raceway surface and the rolling surface are stripped.

In short, when judging whether the bearing can continue to be used, it needs to be comprehensively inspected and evaluated, and judged in accordance with the relevant standards. If the above damage occurs, the bearing must be replaced immediately to ensure the safe operation of the machine and equipment.
