• Important points for bearing installation and maintenance

    From the angle of use, to ensure that the bearing can work reliably, pay attention to the following points: 1. Improve the quality of lubrication, control the pressure, temperature and flow of engine oil, and strengthen the filtration of engine oil. 2. Use fuel and lubricating oil that meet the requirements. 3. Control the temperature state of the diesel generator set, and work under the condition of supercooling and overheating is unfavorable. In cold weather, the diesel engine should be preheated before starting, and the crankshaft should be turned by hand to allow the engine oil to enter th... read more

  • Bearing installation

    Whether the bearings are installed correctly affects accuracy, life, and performance. Therefore, the design and assembly department should fully study the bearing installation. Hope to install according to the operation standard. The work standard items are usually as follows: (1) Cleaning bearings and bearing related parts (2) Check the dimensions and finishing of related parts (3) Installation (4) Inspection after installing the bearing (5) Supply lubricant It is hoped that the bearing packaging will be opened just before installation. General grease is lubricated and filled with grease dire... read more

  • Bearing disassembly

    The disassembly of the bearing is a regular maintenance, carried out when the bearing is replaced. After disassembly, if you continue to use it, or if you need to check the condition of the bearing, the disassembly should be carried out as carefully as when it was installed. Be careful not to damage the parts of the bearing, especially the disassembly of the interference fit bearing, which is difficult to operate. It is also very important to design and produce disassembly tools as needed. When disassembling, study the disassembling method, sequence, and investigate the matching conditions of ... read more

  • Bearing cleaning

    When disassembling the bearing for inspection, first make a record of appearance using photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing. a. The bearings are cleaned by coarse washing and fine washing, and a metal grid can be placed on the bottom of the container used. b. When rough washing, use a brush or the like in the oil to remove grease or adhesion. If you turn the bearing in oil at this time, be careful to damage the rolling surface due to foreign objects. c. When finely washing, slowly rotate the b... read more

  • Bearing inspection and judgment

    In order to judge whether the removed bearing can be reused, it is important to check its dimensional accuracy, rotation accuracy, internal clearance and mating surface, raceway surface, cage and sealing ring. Since large bearings cannot be rotated by hand, pay attention to check the appearance of rolling elements, raceway surfaces, cages, rib surfaces, etc. The higher the importance of the bearings, the more careful inspection is required. Causes of rolling bearing fever and its elimination Low bearing accuracy: Use bearings with specified accuracy grades. The main shaft is bent or the hole o... read more

  • Bearing quality discrimination

    To identify the quality of equipment bearings, we usually proceed from the following aspects: 1. Whether the outer packaging is clear Under normal circumstances, the brands produced by regular manufacturers have their own special designers to design the external packaging, and arrange the factories with production conditions to make production. Therefore, the packaging of the products should be very clear from the line to the color block. unambiguous. 2. Whether the steel printing is clear Each bearing product will have its brand name, label, etc. printed on the bearing product body. Although ... read more
