The choice of non-standard bearing grease and maintenance

The choice of non-standard bearing grease and maintenance source: bearing | last updated: - 2020 09 - 11 non-standard bearing selection, improper lubrication grease in the cause of non-standard bearing premature failure accounted for 36%. General grease can not meet the needs of all kinds of special bearing applications, only use one or all kinds of general application to meet all of the bearing grease, problems will be caused by far outweighs the benefits of unified brand. Bearing application condition is varied, the correct lubrication is grease and bearing application conditions. Bearing grease is to guarantee the reliability of the bearing a smooth, easy operation and have the largest base, even under the most extreme working conditions. Can prevent pollutants from entering the bearing grease, buffer impact load and corrosion resistance. In the actual application to choose the appropriate grease is bearing the basic conditions for maximum service life. Correct selection of lubricant standard includes non-standard bearing type and size, temperature, speed, load and the desired service life and supplemental lubrication cycle. Initial radial clearance of bearing in the process of into reduced gradually, and pushed into the amount of size decide to cooperate. Prior to installation, therefore, must first the initial measurement of non-standard bearing radial clearance. In the process of bearing push, continuously measure the radial clearance, until meet the requirements of radial clearance is reduce the amount and range of the ideal. Due to temperature lubrication, rotational speed, load, the influence of environment, the temperature range of values in the table only said roughly. Bearing lubrication effect of lubrication on the fatigue life of rolling bearing, friction and wear, temperature rise, vibration and so on have important influence, not normal lubrication, bearing cannot work. Analyze the failure reasons of non-standard bearing show that about 40% of the bearing damage is related to bad lubrication. Therefore, good lubrication of the non-standard bearing is an effective measure to reduce the bearing friction and wear. In addition, the bearing lubrication and cooling, a variety of action such as rust, seal, moderate impact. Non-standard bearing maintenance for non-standard bearings and keep its long-term performance into full play, must earnestly to do regular maintenance ( Regular inspection) 。 Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency. Non-standard bearings cleaning non-standard bearings will be removed when checking, use methods such as photography first appearance record. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. A, non-standard bearings cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil bearing, pay attention to the rolling surface due to foreign bodies such as damage. C, fine cleaning, slowly rotating bearings in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. After cleaning, coating anticorrosive oil or antirust grease on the bearing immediately.
