1) needle roller bearings running emergence of rhythmic percussion or percussion may be spalling NSK Bearings Roller Road, indentation, or other components caused by improper installation;
2) needle bearing "bunk cushions, cushions, half-hearted" sound may be caused by bearing Mifengbuyan, lubricating oil is not clean, the bearing clearance is too large;
3) bearing "enjoin squeak, squeak enjoin screaming sound, may be due to the lubricant drying up or lack of lubricant caused;
4) If the bearing has the sound of "Falling", NSK Bearings is not cleaned, the internal mixing due to debris, sand, dust and other debris;
5) bearing inner ring heat over-expansion, friction bearings and seals and related parts;
6) Install the needle roller bearings, due to the beat of the bearings or other parts, causing the bearing deformation;
7) bearing adapter to put on too tight or loose;
8) the size of the bearing box is too large (including the use of larger), causing the needle bearing outer ring of the bearing rotation ...... and so on, are likely to make the bearings produce noise and abnormal sound. Reasons, caused by the vibration of NSK bearings are basically the same as the reason for bearing noise and unusual sound, there is a strong correlation between the two. Vibration frequency, but not in the audio range does not cause noise and abnormal sound.
