Check after the judge removed the koyo bearings can use to clean deep groove ball bearings, carefully check the raceway and rolling surface, with the surface state, the wear of the cage, the increase of the bearing clearance andno damage on the size of the decline in accuracy, an exception. Non-separation of small ball bearings, with one hand, the inner ring to support the level of the outer ring to confirm be rotating smooth.
koyo bearings, and other separation-shaped bearings, rolling element, the outer ring raceway surface were examined. Large deep groove ball bearings can not hand rotation, pay attention to check the rolling element and raceway, cage, rib surface appearance of the importance of bearing the higher the greater the need for careful check
(1) koyo bearing grease (oil) in general to be replaced after 100 hours in the run, after every 500 hours to replace.
(2) flow koyo bearing grease lubrication, running 1500 hours, should be replaced grease filling the oil is not too much or too little, because the grease too much or too little will cause deep groove ball bearing heating. the refueling general lies in the 1/2 to 2/3 of the bearing chamber volume is appropriate.
(3) for lubricating the bearings, the oil should be added to the specified location.
(4) Sheng lubricating oil or grease to be a clean container, usually sealed, there should be no dust, iron filings and other debris, so as not to damage the bearing.
(5) The motor deep groove ball bearings generally use sodium based grease, the characteristics of this grease is to high temperature (125 ° C), but easily dissolved in water, so can not take it for koyo bearing lubrication.
