INA bearing maintenance and overhaul - bearing knowledge

1, eccentric INA bearing maintenance: for as long as possible in good condition to maintain INA bearings have the performance of maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. As maintenance issues in the operation, the rotation of the eccentric INA bearing the sound, vibration, temperature, the state of the lubricants and so on. 2, eccentric INA bearing maintenance: INA bearings cleaning: removing eccentric INA bearings under repair, the appearance of the first record eccentric INA bearings, confirm the residual stock of lubricant, sampling inspection with lubricant, wash the eccentric INA bearings. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the eccentricity of the INA bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the INA bearing is not direct contact with dirt from the container. Rough when cleaning, if rotating the INA bearings with dirt, damage of INA bearings rolling surface, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning is eccentric INA bearings in cleaning oil side spin, side carefully cleaned. In addition, the clean oil is always kept clean. 3, eccentric INA bearing maintenance and judgment: in order to determine whether the INA bearing is removed can use, check after wash INA bearings. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the INA bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation of small ball INA bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. INA bearings taper roller bearing separation form, can be respectively of the rolling elements, the outer ring raceway surface inspection. Large INA bearings can't rotate with the hand, pay attention to check the rolling element and raceway surface, cage, guard surface appearance, such as the importance of INA bearings high must check carefully.
