The importance of the imported bearing high must check carefully

Rolling bearing using a variety of mechanical equipment, imported bearing conditions required by the increasingly stringent market requirements of equipment and other properties, the performance also increasingly diversified. From a large number of structure, size, select the most appropriate bearings, need a different Angle. In choosing imported bearing, it is generally believed that as a bearing imports, the difficulty of installation and removal, imported bearing, and bearing the market size, such as space allows, the general decided to import the bearing structure. In the use of various mechanical design life and various durable comparative study of imported bearing limit bearing, bearing has to be decided at the same time. In choosing imported bearings, bearings are often inclined to think that grease life in aging, the fatigue life of oil, abrasion resistance, low noise, also need to fully research. In addition, according to different purposes, it is a necessary choice for precision, clearance, and keep the frame structure, meet the requirements of the lubricating grease, special design of the bearing. However, choosing bearing no certain order, rules, priority should be given to import bearing the required conditions, performance, and related matters, especially the practical. As long as as much as possible in order to keep intact the original performance of bearing, to maintain, maintenance, in the first place, to prevent accidents, ensure the reliability of operation, improve productivity and economy. Corresponding mechanical operation and maintenance standards, on a regular basis, the best conditions. Including monitoring running state, supplement or replace the lubricant, regular check cleared. As the problem of maintenance operations, has imported bearing rotation, vibration, temperature, lubrication condition, and so on. Bearing cleaning: remove the bearing repair, the appearance of the record for the first time to import bearings, confirm the amount of residual lubricant, sampling inspection after the use of lubricants, cleaning bearing. As a cleaning agent, general use gasoline, kerosene. Remove the bearing cleaning, washing and fine washing thick, be placed in a container, metal openings at the first, make direct contact with imported bearing not dirt container. Rough washing, if the bearing rotating dirt, damage to the bearings rolling surface, it should be noted. In the crude oil washing, brush with the brush, to remove oil, grease, viscous material, generally clean, wash into a fine. Fine wash wash oil is in the side of the bearing rotation, while carefully cleaned. In addition, clean the oil must be kept clean bearing maintenance and judgment: to determine whether to remove the bearing can be used to check the bearing after cleaning. Check the raceway, raceway, surface state, cage wear, imported bearing clearance and to increase the dimension precision, has not damage, abnormal. Non separation of small ball bearings, inner ring, with one hand support level, rotate the outer ring to confirm smoothly. Separation of tapered roller bearings and bearing, rolling your body, the outer ring raceway surface inspection. Large bearings, because they can't rotate with the hand, pay attention to check the raceway of roller and cage, metope, such as the appearance, the higher the importance of imported bearings, check more carefully.
