For deep groove ball bearing facility periodic inspection repair, operation and other external parts of deep groove ball bearings are removed when you change when the purposes of investigation, demand in turn determine whether deep groove ball bearing parts can be used again and recorded using state of things good from bad. Also to be carefully investigated and documented SKF bearings were removed and the appearance of things. In order to identify and investigate the remaining quantity of lubricant agent, sampled recently, good cleaning deep groove ball bearings.
　　Second investigation of deep groove ball bearing Raceway surface, rolling surfaces and appropriate surface wear and maintain the State of exception and there is no default injury situation and in particular to look carefully at the Raceway surface running track. Judgment bearing will use again, to think about the issue of bearing damage level, machine performance, secure, operating conditions, seizing cycle back to vote again.
　　Final results of the investigation, if it is found to deep groove ball bearings are damaged and abnormal situation, in accordance with the FAG bearings damage inspection clearly duanyou to develop countermeasures. Additional, final results of the investigation, if there is any bottom several short, deep groove ball bearings cannot be used, needs new bearing change.
　　A. inside ring, rolling elements, maintain that regardless of what one has revealed cracks and debris.
　　B. inside ring, rolling elements regardless of what a fall off in it.
　　C. Raceway surface, rib and rolling with significant injuries.
　　D. maintenance wear serious nail loose interest or Willow.
　　E. Raceway surface, rolling rust and scars.
　　F. a significant indentation on the rolling surface and rolling and hit mark.
　　G. on the inner or outer ring outside diameter inner diameter surface creep.
　　H. overheating color interest.
　　I. lubricating oils tightly closed tightly closed ring bearings and dust cap damaged seriously.
Grease two issues, one is required by the car manual, selection of appropriate grades of lubricating grease. For example, a car water pump bearings should not be selecting m. Mounir Bouchenaki grease, because of its poor water resistance. II was joined in deep groove ball bearing grease to just the right amount, generally filling cavities of deep groove ball bearing 1/2-l/3 suitable, too much is not only useless, also increase the functioning of bearing resistance, warming heat. Notably is the wheel hub bearing, promotion of "air hub lubrication", that is, only in deep groove ball bearing coated with a layer of the right amount of grease can, otherwise, is not only a waste and poor cooling, also causes the heated lubricating grease spills that may affect braking performance.
Advantage of friction resistance of lubricating and cooling, mainly used in high-speed and high ambient temperature deep groove ball bearings. Grades required by the car manual selection of lubricants and automobile maintenance cycle and change, and released after cleaning the body after the old oil with new oil, oil should be added to the prescribed marking, or flush with the filler (as the car specific structures, requirements may be), not more.
　　Keep rack assemble precision relying on private assembly positioner guarantees, fully guaranteed NSK bearings Assembly accuracy. Fixed ring of small interference conditions are matched high shape accuracy and smaller for both surface roughness, otherwise result in installation difficulties and removal more difficult, and in addition, you also need to consider the impact of thermal elongation of the main shaft.
