In order to determine whether removed koyo bearing can be used again, check after wash deep groove ball bearings, carefully check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the bearing clearance, and presence of dimensional precision, abnormal falling damage. Not separated type ball bearing, the inner ring with one hand support levels, rotate the outer ring confirm whether smooth. Koyo bearing separation type bearing, rolling body, the outer ring raceway surface can be respectively. Large deep groove ball bearings can't rotate with the hand, pay attention to check the rolling element and raceway and the appearance, such as, cage, guard shall carefully check the importance of bearing the high ( 1) Koyo bearing new pump put into use, must be replaced after running 100 hours (grease Oil) 1, 500 hours after each run. ( 2) Flow koyo bearing is lubricated by grease, run after 1500 hours, should be replaced, grease filling the oil amount is too little or too much, because too much or too little can cause deep groove ball bearing grease fever, amount to general in bearing chamber volume 1/2 ~ 2/3 is advisable. ( 3) For bearing is lubricated by lubricating oil, the oil should be added to the specified location. ( 4) Containers of lubricating oil or grease to clean, should be sealed at ordinary times, should not have dust, iron and other sundry, in order to avoid damage to the bearings. ( 5) Deep groove ball bearing motor generally USES sodium base grease, this kind of ability is the feature of high temperature grease ( 125℃) , but easy to dissolve in the water, so can't use it for koyo bearing lubrication.
