Full install IKO bearing with the correct method of bearing service life

In principle, all IKO bearing before installation should be stored in their original packaging. They need to stay clean, no moisture, relatively constant temperature environment. Rolling bearing should stay away from dust, water and corrosive chemicals. Shaking and vibration may never destroy IKO bearing mechanical properties, so the vibrations must be avoided in the process of handling and storage. Basically, all IKO bearings must be level to save, because some of the heavier bearing long upright, may deformation due to its own weight. In advance (coated with grease Or sealed) IKO bearings need to be especially careful, because the grease will change after long time of storage density. So when IKO bearings used for the first time, there will be a certain degree of rotation noise. As a result, the IKO bearing on time should be controlled according to the principle of first in first out. Clean clean is very important for NN rolling bearing. IKO bearing ring rotation surface and the surface roughness of the rolling element is usually a 1/10 microns, such a smooth surface is sensitive to damage caused by pollutants. Lubrication layer between the rotation surface usually is 0. 2 ~ 1 microns, is greater than the lubricant type size particles of impurities are influenced by the excessive rolling rolling element and the partial pressure in IKO bearing steel, eventually lead to permanent material fatigue. In addition to this, the external environment of dust particle size can be up to 10 microns, also can cause damage of IKO bearing. Therefore, clean dust-free environment for storage and installation of the bearing is very important. IKO bearing should use the right tools carefully install and remove. Industry experts estimate that 16% of premature bearing failure is due to incorrect installation. For large installation ( In the production plant, for example) Installation, usually we will strictly control conditions, also can use appropriate IKO bearing installation equipment. But, in the maintenance or replacement work, the environment is varied. Therefore, in order to ensure the longest IKO bearing service life and comprehensive preparations for bearing installation is necessary. First, the relevant documents, such as drawings, maintenance manual, product manuals, etc need to carefully study. Next, all IKO bearing components, such as shaft, spacer ring, must be perfectly clean, cover, washer, etc from pollution. The condition of adjacent parts also check carefully. In order to determine whether removed IKO bearings can be used again, check after wash bearing. Carefully check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, IKO bearing clearance increases, and presence of dimensional precision falling damage, abnormal. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. IKO bearings taper roller bearing separation form, can be respectively of the rolling elements, the outer ring raceway surface inspection. 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 IKO bearing high must check carefully. Whether can be used to judge, is to think about IKO bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. But, if you have the following defects cannot be used again. Have to change new IKO bearings. Inner ring and outer ring, rolling element and cage there is crack on any one, or gap. Ring, rolling body fracture on any one. Raceway surface, guard, with significant rolling body relaxation. Raceway surface rust, rolling body, injury. On the raceway surface, rolling body has serious indentation and playing. Inner ring diameter or outer diameter surface has obvious creep. Due to the hot color is obvious. The IKO bearing grease sealed, sealing ring, or dust cover breakage is obvious.
