Cooling Fan Noise - Sleeve Bearing vs Ball Bearing
Introduction Quite often in low-flow electronic cooling fans for computers, where the aerodynamic noise is low, the predominant noise emitted by the fan is generated in the bearing system. This type of fan usually has either an oil-impregnated sleeve bearing or ball bearings. Both bearing systems create noise that can be very different in both frequency content and amplitude.

Using Vibration Analysis To Detect Early Failure Of Bearings
The vibration signal from the early stage of a defective bearing may be masked by machine noise making it difficult to detect the fault by spectrum analysis alone. The main advantage of envelope analysis is its ability to extract the periodic impacts and the modulated random noise from a deteriorating rolling bearing.

Typical bearing defects and spectral identifiion | Power-MI
Excessive bearing internal clearance. Usually features a spectral signature characterized by the presence of synchronous vibration (rotating speed harmonics), subsynchronous vibration (0.5x RPM) and non-synchronous (1.5x RPM, 2.5xRPM, 3.5x RPM, etc.) . These frequencies sometimes can be modulated by the FTF. Looseness between bearing and shaft

[PDF] Sound and Vibration in Rolling Bearings | Semantic
In the midst of such advancement, demand has grown for rolling bearings with lower vibration and noise. In response, extensive research and development has been undertaken at NSK. This report summarizes some of the key findings accumulated from research on sound and vibration in bearings, and discusses vibration modes of bearing rings.
Vibration in Bearings - Calculations for Bearing Defect
As the bearing deteriorates further, 1 x rpm sidebands develop, especially around the inner race frequencies. This is due to amplitude modulation as the defect (s) passes in and out of the "load zone." They can occur at +/- 1 x rpm, +/- cage frequency, or +/- ball spin frequency, depending on the situation. Stage Three:
Electrical motor bearings vibration and noise | dynamic
Vibration and noise is playing more and more important role of dynamic performance of rolling bearing. To avoid the bearings failed in the early stage, as well as to waste the more energy consumption, the vibration and noise measurement is the essential process to control the good operation bearings. vibration and noise measurement is the essential

Ball Bearing Noise | Lily Bearing
Ball Bearing Noise. Bearing acoustical noise is a function of both the bearing itself and the way in which it is used. Bearings can be specified as 100% noise-tested during manufacture. Bearing noise is not generally influenced by ABEC precision, but rather by manufacturers'' internal quality standards, particularly raceway finish.
