P18 Infrared thermometer with laser targeting P19 THE ADVICE OF THE EXPERTS Mounting a bearing an essential stag correct operation of the installation 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 t 1 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
