Imported bearing maintenance and cleaning

In order to judge whether the imported bearings of the removed can be used again, check after wash bearing. Carefully check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase in the imported bearing clearance, 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. Separation of tapered roller bearings and bearing, rolling body, the outer ring raceway surface can be respectively.
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 bearing high must check carefully.
Whether can be used to determine, is considering import 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. Must change new bearing. 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 bearing grease sealed, sealing ring, or dust cover breakage is obvious Inner Diameter of SKF Bearings skf-ball-bearings.com/bearings.php.htm.
Imported bearing cleaning
Remove the import bearings under repair, the first record bearing appearance, confirm the stock of lubricant residues, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, coarse and fine fine cleaning cleaning, 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. When cleaning, if to spin bearing with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning).
