Solve the FAG oilless bearing burn correct lubrication method

Although you can install 'free' for all kinds of FAG bearing seal, but no early failure is still 36% of oil bearing and improper use is not correct grease technology. Any improper lubrication of bearings in normal life inevitably fail to move forward. Machinery and equipment bearing is usually the most difficult part of the work, have no fixed lubrication will be a problem. Artificial maintenance, is impossible to achieve, the automatic lubrication system, can develop in order to achieve the best lubricating effect. Need grease, tools and effective lubrication technology, will help to significantly reduce downtime. Oilless bearing parts in use under the influence of abnormal high temperature, cooling, without timely and will generate a high temperature tempering parts surface organization or secondary hardening phenomenon called burns. Burns, the main reason is poor lubrication, neck too much load, improper clearance choice, FAG bearings misallocation, raceway surface contact undesirable, such as stress caused by a cold. Such as; 1) In swimming axial bearing, if the external fit too tight, cannot move in casing hole; 2) Bearing in operation temperature, thermal expansion of the shaft causes large axial force, and FAG bearing not axial movement; 3) Due to insufficient lubrication, or lubricant selection is not reasonable, quality problems, such as aging and deterioration; 4) Operation of internal cause and external cause temperature difference is big, improper selection and clearance external cause expansion of small internal cause big show interference lead to FAG bearing temperature rise sharply; 5) Without oil bearing load is too large and uneven distribution of cutting load, the formation of stress concentration; 6) Rough machining parts surface, resulting in poor contact or oil film forming difficulties. Burn appearance characteristics can be judged according to the color of the surface of the small with. FAG bearing in use due to reasons such as lubricant, temperature, corrosion, change parts surface, mainly with light yellow color, yellow, palm red, purple, blue and dark blue, light yellow, yellow, palm red chips in color ( See the related content) , if appear purple blue or bluish black action for burns. Burns easily cause the loss of parts surface hardness or a tiny grain. Burn the place mainly in parts of the contact surface, such as taper roller bearing guard working face, talk about child face, the stress concentration of the surface of the rolling, etc. Burn prevention according to the causes of burns a targeted action. Such as the right to choose oil-free bearing structure and configuration, avoid FAG bearing with large installed load, when the right way to prevent stress concentration, ensure lubricating effect, etc.
