As the bearing rotates, individual ball loads, hence elastic deflections at the rolling element raceway contacts, changeproduce relative movement between the inner and outer rings.

The movement takes the form of a locus which under radial load is two dimensional and contained in a radial plane whilunder misalignment it is three dimensional.

The movement is also periodic with base frequency equal to the rate at which the rolling elements pass through the load zone. Frequency

Under radial and misaligned loads bearing vibration is an inherent feature of rolling bearings even if the bearing isgeometrically perfect and is not therefore indicative of poor quality.

This type of vibration is often referred to as variable compliance and occurs because the external load is supported by a discrete number of rolling elements whose position with respect to the line of action of the load continually changes with time.

Nowadays, although the amplitudes of surface imperfections are in the order of nanometres, significant vibrations can stillbe produced in the entire audible frequency range (20Hz – 20kHz).

The level of the vibration will depend upon many factors including the energy of the impact, the point at which the vibration is measured and the construction of the bearing.

Rolling contact bearings represent a complex vibration system whose components i.e. rolling elements, inner raceway, outerraceway and cage interact to generate complex vibration signatures.

Although rolling bearings are manufactured using high precision machine tools and under strict cleanliness and quality controls, like any other manufactured part they will have degrees of imperfection and generate vibration as the surfaces interact through a combination of rolling and sliding.

This often makes the interpretation of vibration data difficult other than by a trained specialist and can in somesituations lead to a misdiagnosis resulting in unnecessary machine downtime and costs.

In this article the sources of bearing vibration are discussed along with the characteristic vibration frequencies that arelikely to be generated.

Vibration monitoring has now become a well accepted part many planned maintenance regimes and relies on the well known characteristic vibration signatures which rolling bearings exhibit as the rolling surfaces degrade.

However, in most situations bearing vibration cannot be measured directl and so the bearing vibration signature is modified by the machine structure and this situation is further complicated vibration from other equipment on the machine i.e. electric motors, gears, belts, hydraulics, etc. and from structural resonances.

It is now generally accepted that quiet running is synonymous with the form and finish of the rolling contact surfaces. As aresult bearing manufacturers have developed vibration tests as an effective method for measuring quality. A common approach is to mount the bearing on a quiet running spindle and measure the radial velocity at a point on the bearing outer ring in three frequency bands, 50-300, 300-1800 and 1800-10000Hz.

The bearing must meet RMS velocity limits in all three frequency bands.

Rolling element bearings are often used in noise sensitive applications e.g. household appliances, electric motors whichoften use small to medium size bearings.

Bearing vibration is therefore becoming increasingly important from both an environmental perspective and because it is synonymous with quality.

Many bearings fail prematurely in service because of contamination, poor lubrication,misalignment, temperature extremes, poor fitting/fits, shaft unbalance and misalignment. All these factors lead to an increase in bearing vibration and condition monitoring has been used for many years to detect degrading bearings before they catastrophically fail, with the associated costs of downtime or significant damage to other parts of the machine.
