What are the Main Causes of Noise and Abnormal Sound in Spherical Roller Thrust Bearings?

The use of good performance of the spherical roller thrust bearings, generally speaking, there is no abnormal sound when running.

1) If there is a rhythmic knocking sound or impact sound when the bearing is running, it may be due to bearing raceway stripping, indentation or other parts improperly installed.

2) found that the bearing has a "gloop, gloop" sound, may be due to poor sealing of the bearing, lubricating oil is not clean, bearing clearance is too large caused by.

3) found that the bearing has "squeaking, squealing" sound, may be due to the lubricant dry or lack of lubricant caused by.

4) If the bearing is found to have a "sand sand sand" sound, may be the bearing is not clean, mixed with internal abrasive, sand, dust and other debris caused.

5) bearing inner ring heat over-expansion, bearing and seals and related parts friction.

6)When installing the bearing, due to knocking the bearing or other parts, causing bearing deformation.

7)The tightening sleeve of the bearing is too tight or loose.

8) bearing box size is too large (including the use of larger), causing the outer ring of the bearing in the bearing housing rotation, may make the bearing noise and abnormal sound.

The cause of the spherical roller thrust bearings vibration, basically the same as the cause of bearing noise and abnormal sound, there is a strong correlation between the two. But not in the audio range of the vibration frequency, it will not cause noise and abnormal sound.
