Koyo smooth sound cleaning maintenance of deep groove ball bearing grease maintenance

Removed in order to distinguish the koyo bearing could be used again, check in deep groove ball bearings after washing clean, carefully check the raceway surface, rolling surface, cooperate with the state, adhere to the wear condition, the increase of the bearing clearance, and presence of damage, abnormal about dimension precision landing. The separation type ball bearing, the extent of support to inner ring with one hand, rotate the outer ring can confirm fluently. Koyo bearing type bearing separation, able to roll body, the outer ring raceway surface check respectively. Large deep groove ball bearings can't rotate with the hand, pay attention to check, raceway and roller, frame, guard surface appearance, such as the importance of the bearing is higher the more prudent checking ( 1) Koyo bearing new water pump put into use, common in 100 hours after operation to smooth change fat ( Oil) 1, operating 500 hours after each change. ( 2) Adopts smooth fat smooth activity koyo bearing, motion after 1500 hours, should be smooth change fat, filling the oil amount is too much or too little, because the smooth fat too much or too little will make deep groove ball bearing heating, amount to 1/2 ~ 2/3 normal control in bearing chamber volume is advisable. ( 3) On smooth with smooth oil bearing, oil should be added to the rules. ( 4) Containers of smooth smooth oil or grease to clean, normal should be sealed well, should not have dust, iron and other sundry, in order to avoid damage to the bearings. ( 5) Deep groove ball bearing motor common smooth using sodium based grease, this kind of smooth fat feature is the ability of high temperature ( 125℃) , but easy to dissolve in water, so you can't make it smooth for koyo bearing.
