Analyze the precautions for the use of roller conveyor equipment bearings

Roller loading conveyor equipment bearings are precision parts, improper use will not get the expected high performance. The precautions for the use of the bearing are as follows: 　　 (1) Avoid strong impact on the bearing during use, which will cause scars and indentations to become the cause of the accident. In severe cases, it will crack or break.　　(2) Keep the roller bearing and its surroundings clean, and keep the surroundings of the roller clean to prevent dust from entering the bearing.　　(3) Pay attention to the rust of the bearing. Hand sweat can be the cause of rust when handling the bearing. Be careful to operate with clean hands and try to wear gloves.　　(4) Appropriate operating tools must be used, and replacement of existing tools must be avoided.　　(5) Users should be familiar with roller conveyor bearings, regularly replenish lubricants, and formulate operating specifications for bearing use.　　Second, failure and failure reasons　　Due to the different structure and use of rolling bearings, the reasons for their failure are diversified. Mainly include: poor assembly, poor lubrication, overload, impact, vibration, abrasive or harmful liquid intrusion, environmental temperature is too high or too low, material defects, low manufacturing precision and the role of stray current.　　 Due to the complexity of the working conditions, two or more failure mechanisms may work at the same time. In some cases, it appears as a single failure mode, and in other cases, it shows a combination of multiple failure modes.　　3. Precautions before bearing installation　　(1) Preparation of bearing　　Because the roller bearing is rust-proof and packaged, do not open the package before installation. In addition, the anti-rust oil coated on the roller bearing has good lubrication performance. For general-purpose bearings or bearings filled with grease, it can be used directly without cleaning. The bearings are easy to rust and cannot be left for a long time.　　(2) Inspection of shaft and housing 　　 Clean the shaft and housing to make sure that there are no scars or burrs left by machining. There must be no grinding, molding sand, cutting chips, etc. in the shell. Secondly, check whether the size, shape and processing quality of the shaft and the shaft shell conform to the drawings.
