General demolition of INA bearings maintenance, you first need to record it (bearing) appearance, confirm that the residual amount of the lubricant, after sampling check of lubricants, cleaning INA bearings. As a cleaning agent, mostly use both gasoline and kerosene.
Removed INA bearing cleaning, washing can be divided into coarse and fine-wash, first put down INA bearing separately in containers, metal mesh on the bottom first, INA bearings does not directly contact the dirt container. Rough when washing, if you rotate the bearings with dirt, can damage the rolling surface of the bearing should be protected. In crude oil wash, using the brush cleared off grease, stickers, generally after a clean, precision washing process.
INA bearing maintenance and judgment: in order to determine whether removing INA bearings can continue to be used to check after INA bearings clean. Check on Raceway surface, rolling, the status of the mating surfaces, cage wear, increased bearing clearance and has nothing to do with dimensional accuracy drop damage, the exception. Non-separation of small ball bearings, the inner ring with one hand supporting level, rotating outer ring to confirm fluency. Separation such as tapered roller bearings-bearings, rolling elements, the outer of the Raceway surface can be respectively checked.
