The calculation method for the basic rated load of INA bearing is suitable for the high-quality hardened steel commonly used by Dangdang, which is manufactured according to a good processing method, and the rolling contact surface is basically a conventionally designed rolling bearing. Beyond the above specified range, bearing load capacity will be affected. Influence of material The bearing steel has different smelting methods, and the size, enactment and content of inclusions in the material are also different. This difference in village quality can have a beneficial or adverse effect on the bearing capacity of the bearing. If ordinary electric furnace bearing steel is used, the load capacity of the bearing will drop to varying degrees. On the contrary, if the bearing steel smelted by methods such as vacuum remelting, electroslag remelting, etc., or other equivalent materials, the load capacity of the automotive bearing will be improved to varying degrees. The effect of temperature The average bearing can withstand an operating temperature of up to 120 ° C (outer ring measurement temperature of 100 ° C). For working conditions above this limited temperature, bearings made with special heat treatment or special materials shall be used.
In addition to the INA bearing assembly surface and the matching surface of the parts to be cleaned, pay attention to the surface of the journal, the housing hole, the shoulder end face, and the connecting parts such as bushings, washers, end caps, etc. ? If you have any, you can use a fine smash, light sanding, and then install. Rolling bearings are precision components and their use must be carried out with care. No matter how high-performance bearings are used, if not used properly, the expected high performance will not be achieved. The precautions for the use of automotive bearings are as follows:
1, use the appropriate operating tools
Avoid using existing tools and use the right tools.
2, keep the bearings and their surroundings clean
Even small dust that is invisible to the eyes can have a bad effect on the bearings. Therefore, keep the area clean so that the dust does not intrude into the bearing.
3. Use with caution
In the use of the INA bearing strong impact, it will produce scars and indentations, which is the cause of the accident. In severe cases, cracks and breaks occur, so care must be taken.
