NTN bearing joints the maintenance and overhaul of basic steps

NTN bearing for maintenance, maintenance and repair to ensure the reliability of operation, improve the productive development and economy in order to prevent accident, to ensure the reliability of operation, increase productivity, economy, and can ensure the long term joint bearing in good condition to maintain the performance of the original. Bearing cleaning: common use gasoline, kerosene as ordinary cleaner. Remove the NTN bearing under repair, the first record the appearance of the bearing, confirm the residual stock of lubricant, sampling inspection with the lubricant and then began to wash the joint bearing. Cleaning rough washing and fine washing, respectively in the container, first put on the metal mesh at the bottom of the bearing is not direct contact with dirt from the container. 1, in the process of using the bearing, regular cleaning is very first. How accurate cleaning bearing? Joint bearing will be removed when checking first, with the way such as photography first and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. 2, NTN bearing cleaning rough washing and fine washing suspension, can be put in use at the bottom of the container and on the metal frame. 3, rough washing, in oil partly brush eliminate grease or adhesive. If at this time in oil migration transition joint bearing, note due to foreign bodies such as blending mutilate rolling surface. 4, fine cleaning, slowly in the oil migration change bearing, must be hard to stop. 5, daily use of cleaning agent for neutral aqueous diesel or oil, according to the demand is also sometimes use warm lye, etc. No matter use which kinds of detergent, often should clean filter confrontation. 6, after cleaning, immediately on the joint bearing coating anticorrosive oil or antirust grease. NTN bearing inspection and judgment: in order to judge whether the bearing of the removed can use, check after wash bearing. Maintenance content including: monitoring operation status, supplement and replacement of lubricants, sealed, check regularly, it is to maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. As maintenance issues in the operation, has the sound, vibration, temperature, lubricant, joint bearing separation type bearing, rolling body, the outer ring raceway surface can be respectively. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the NTN bearing clearance and has nothing to do with size precision falling damage anomalies. Non separation of small ball bearings, with one hand will support level, the inner ring spinning outer confirm whether large bearing 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 joint bearing high must check carefully.
