SKF bearing failure scale factors and a maintenance process in advance - bearing knowledge

SKF bearing failure scale factors in advance: improper lubrication: 36% of bearing failure reason in advance. In domestic problems will be bigger, estimated to account for 40 - 50%. Problems include insufficient lubrication, excessive lubrication, the lubricant into the impurities, improper lubricating and so on. Pollution: 14% of bearing early failure reason, main seal failure problem, man-made pollution and operating environment smudgy, etc. Fatigue: 34% of bearing failure reason in advance. SKF bearing maintenance process: SKF bearing store environment: SKF bearing maintenance is disassembled, how to judge whether the bearing can also use the bearing network according to the understanding of the use of SKF bearing summed up the following: 1, the inspection, bearing a is removed before it hasn't been cleaned in the net, don't say whether it could also use again, treat it as new. 2, the heart is not to turn a dirty bearing, can turn when cleaning. Cleaning solvents should use petroleum base, to the net and lint-free cloth or can be used to clean and not compressed air with moisture I. 3, the heart be careful cleaning process, detergent has damage to the skin, and try to wear protective gloves and goggles. 4, check the bearing, a probe for small mirror and similar to the dentist to check bearing raceway, cage with roller, it is important to pay special attention to the scratches, marks, cracks, color change, look to whether still keep have like the surface of the mirror sample and so on. 5, toggle bearings, listening to the sound of it. An undamaged bearing, no scar and no other defects, clearance is not too large, operation is stable, that the bearing can be turned back again. 6, to prevent the occurrence of corrosion, should immediately after cleaning bearing lubrication.
