P18 Infrared thermometer with laser targeting P 19 Mounting a bearing essential stage which determines span and correct operation of the installation gt The monitoring of the millions of NTN SNR bearings sold has allowed us to establish very precise statistics on the origin of faults This collection of data highlights one essential fact it is rare that the bearing itself is the cause of a premature failure In 90 of cases the cause can be found in external components which can be classified into four categories INADEQUATE LUBRICATION 55 Inadequate or poor lubrication severely reduces the working life of a bearing It is often neglected because of bearing accessibility problems and a lack of knowledge about lubricants on the part of the user The choice of lubricant the method the quantity to apply to the bearing neither too much nor too little and the monitoring frequency must be properly studied NTN SNR offers you a special service and markets a complete range of greases covering all applications as well as an automatic greasing system POLLUTION 18 The environment in which bearings operate is often highly polluted Dust liquid detergents and other contaminants can severely reduce the working life of a bearing To deal with these problems NTN SNR has developed a comprehensive range of sealing systems and will be pleased to advise you on the best c

Excessive impacts during mounting or forces causing rings and seals to break or races to become indented e The accidental introduction of particles or liquids present in the mounting environment OUR RECOMMENDATIONS pis rule the bearing must be firmly fixed to the rotating part Rotation analysis Load fixed in relation to the outer ring Inner ring tightened onto the shaft Load fixed in relation to the inner ring Outer ring tightened into its housing end rule Mounting is carried out using impact rings applied to the bearing ring which has the tightest fit This avoids stressing the rotating body and damaging the bearing gt Special case of a long shaft for an assembly requiring a longitudinal adjustment of the bearing it is preferable to use a mechanical coupling with a tapered seat joined to a bearing with a tapered bore D An COLD D sized THE WORDS OF AN NTN SNR EXPERT For easier mounting and to avoid contact corrosion of the shaft or the housing always use an anti fretting paste This thick lubricant helps preserve the quality of parts surfaces subjected to sliding forces Without this paste corrosion will gradually increase the play between the bearing and the shaft or housing ultimately causing vibration and even the premature deterioration of the bearing and its mounting surfaces Avoid introducing contaminants when mounting swarf liquid
