1) scar sound and control method

Rolling bearing surface such as rolling FAG have crack, impress or corrosion, will take place as  rivet that periodic vibration and noise, and its period may be fixed with a certain speed but most of the corresponding relationship, the scar in the channel will continuously happen, the scar in the steel ball on the scenery and the noise with the installation and lubrication condition and have certain change. This kind of noise control methods are: when installation, do not knock bearing, bearing shaft assembly then in housing after when installed to prevent bearing inclined; Prevent bearing corrosion and inventory when transported to prevent shock vibration; Use high viscosity of grease.

(2) the dust sound and control method

SKF bearing such as dust in rolling foreign body, will occur the periodic vibration and so-called dust sound, its vibration and noise of size and uncertain, and with little or no. Dust the control method of sound: improve the cleaning methods of bearing, before installation, shaft bearings are a hole, and all parts strictly clear ShenJieJing match; Remove the lubricant in foreign body; Improve the bearing seal; Avoid the use of material is not pure or studded with foreign body maintains a plastic.

(3) the lubrication factors caused noise and the countermeasures

Choose wrong, lubricants inadequate happen or aging scleroma, can lead to a bearing vibration and noise, and the noise no certain discipline. For this situation, only suitable lubricants, adjust the lubrication dose, prolong the service life of the lubricant and reasonable change cycle.

And the host of the noise and its countermeasures

 
This noise is not only caused by IKO bearing, and from single to trace the reason is bearing futile, deal with host full attention and, when necessary, to improve the performance of the host. The main narrative motor of common hum and frame resonant voice.
