How to judge is removed after the maintenance and cleaning of bearing

How to judge is removed after the maintenance and cleaning bearing ( 轴承) Whether to use ( 使用) ? There is a FAG bearing damage, need to consider machinery ( 机械) Performance ( 兴能) , importance, and operating conditions, to the next overhaul period. Such as cross section thin-walled bearing has realized the extremely thin cross section of the bearing, also has realized the product miniaturization, lightweight. The diversity of products extends its application scope. It is generally divided into glue sealing - RS, iron seal - ZZ, plane, canvas - K, copper - M。 However, if found the following bearing ( 条件) When bearing can no longer use, must be replaced new SUNTHAI F& F bearing: 1, SUNTHAI F& F bearing inner ring and outer ring, rolling element and cage there is crack on any one, or gap, need to change new 2, ring, rolling body fracture (on any one fracture) 3, raceway surface, guard, with significant rolling body relaxation; Rust, injured; Have serious indentation ( 缩进) And mark 4, inner ring diameter or outer diameter ( The outer diameter) Surface has obvious creep ( 蠕变) ； Lubrication (sealed lubrication) Bearing grease ( 轴承) Seal ( 密封) Circle, or dust cover breakage is obvious 5, bearing ( 轴承) Due to thermal discoloration SUNTHAI obviously, F& F bearing ( 轴承) Cleaning rough washing and fine fine washing machine has two, 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. Bearing bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication. In the coarse clean oil, use the brush to remove ( 清除) Lubrication ( lubrication) Oil, adhesive, after clean, roughly into fine cleaning). In essence when cleaning, if to spin bearing with dirt ( 旋转) , will damage the bearing rolling surface, should pay attention to ( 注意) 。 Fine cleaning, FAG bearing side rotation in the cleaning of oil, while carefully cleaned. Also, cleaning oil always kept clean.
