With some smooth agent friction between two fingers, if the presence of pollutants, is to find out; Or in the back of a thin layer of smooth agent, then stop light inspection.
If already presents the adverse conditions, be sure to switch off, and bad seal will incur import bearing damage, the bearing cloud is not normal and forming equipment downtime. So when we on
bearing stop check before, should lead to clean bearing appearance, then remove the perimeter of the bearing parts. Everybody wants to pay attention to, oil seal is very fragile parts, thus in the check and demand exceptionally careful when disassembling, do not excessive force, so as to avoid formation damage to parts.
Then carefully check bearing oil seal and the surrounding parts, second, we need to check the bearing smooth agent.
1, bearing the: care for as long as possible in good condition to maintain the performance of the bearing was must care and maintenance, in order to prevent accidents from already, to ensure the reliability of operation, consumer and economy progress. Enjoy the best conditions of mechanical operation of the corresponding operation standard, suspended on a regular basis. Content includes monitoring running state, supplement or a change in lubricant, sealed, check regularly. Points for maintenance operation, have bearing rotating the sound, vibration, temperature, the state of the lubricants and so on.
2, bearing maintenance: bearing cleaning: removing bearing under repair, the appearance of the first recorded bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to import bearings cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, assuming that spin the bearings with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean oil, use the brush clean up to grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, bearing side rotation in the wash oil, serious cleaning. In addition, cleaning oil often should insist on cleaning.
3, bearing maintenance and discriminant: removed in order to distinguish the bearing whether can use, check after wash bearing. Examination of raceway surface, rolling surface, cooperate with the abrasion of the state, adhere to the rack, the increase of the bearing clearance and has nothing to do with dimension precision landing damage, abnormal. The small ball bearing type respectively, then the inner ring with one hand support level, rotate the outer ring can confirm fluently.
