Why only one side sealed deep groove ball bearings with grease

Why only one side sealed deep groove ball bearings with grease in the process of using deep groove ball bearings, we occasionally pry bearing seal the lid, then we will find some bearing side full of grease, but on the other side is no grease; And some are even on both sides bearing is oil distribution, especially the bearings with high price, what reason is this? We know that the bearing in the process of operation is to grease lubrication and rust, especially the sealing of deep groove ball bearings, can't high-speed operation, without oil bearing life is greatly shortened. And bearing in the process of production is a process, to a bearing inner and outer ring and ball and cage assembly, the first is to wash, rinse after pressure seal the lid of the part, to turn the bearing over again, grease, Usually add bearing internal volume of 30% ~ 35%) And then press the lid. Here we found that the sealing deep groove ball bearing in the process of production have side is without grease, only one side to the grease. If add oil on both sides, bearing more is in the process of production procedure, this will reduce the production efficiency. Someone will ask, why are some bearing on both sides will have a fat? If there is oil bearing sealing ring on both sides, this is a relatively high price, another is bearing used. Why do you say that? Is that the high price bearing general quality is better, this kind of deep groove ball bearing on one side, after a full inspection, will be after rotation test of bearing, bearing rotation after the fats are distributed evenly; Another is the bearings used, second-hand, grease is certainly will be distributed evenly. So says the new oil deep groove ball bearings are only one side but on the other side is not normal, consumer also need not worry, it's only a few take bearing rotation, or a few minutes to get the mechanical rolling, the inside of the bearing grease is uniform rotation, does not affect use. Bearing on production of 2 mm diameter 30 ~ 40 mm 30 small small-sized bearing, has high precision, small vibration, low noise, high performance, high speed, long life and other excellent features. Widely used in household appliances, electric tools, small-sized electric machinery, fitness equipment, office automation equipment, medical equipment, instrumentation, internal combustion engines, construction machinery, railway vehicle, loading and unloading handling machinery, agricultural machinery, all kinds of industrial machinery, etc. Buy miniature bearings, motor bearings, deep groove ball bearing, please find bearing.
