What are the five basic characteristics of self-aligning roller bearings

Five basic characteristics of self-aligning roller bearings. For self-aligning roller bearings, if rolling friction occurs during use, it will be accompanied by sliding friction, which will increase bearing wear. In order to prevent or reduce bearing wear and maintain high-precision stability, the premise is to choose high hardness, strong rust prevention performance, high wear resistance, contact fatigue strength, and first-class processing procedures. These conditions are the basic performance of self-aligning roller bearings

  • When using self-aligning roller bearings, the hardness of the bearing is one of the key points of the whole bearing quality. Generally, the hardness of the bearing should reach hrc61~65 in the process of use, so as to better achieve the expected effect, and play a larger elastic buffer in high-strength contact fatigue and wear resistance.
  • In order to prevent the bearing from corrosion and rust when using the bearing, especially in the processing or storage of bearing parts and finished products, we should choose bearing steel with high rust prevention performance.
  • When using self-aligning roller bearings, one of the headaches is the wear resistance of the bearings, and the wear resistance is also a question often asked by users when buying bearings. This is mainly due to the rolling friction and sliding friction between the rings, rolling elements and cages of the bearings in the process of use, and this kind of friction, as mentioned at the beginning, is due to the unstable wear resistance of the bearings, which cannot achieve the expected effect, To prevent the damage caused by friction, we must work hard on the selection of bearing steel, which should have strong wear resistance.
  • Why should we improve the service life of self-aligning roller bearings! The main reason is that in the process of use: under the action of periodic load, the bearing will easily cause damage, even cracking and spalling after contacting with the contact surface. Therefore, in order to prevent such accidents, when selecting or using self-aligning roller bearings, we should choose ones with strong contact fatigue, so as to effectively prolong the service life of the bearings.
  • In addition to the above requirements, the machining performance of self-aligning roller bearings should be strictly controlled, which is also to ensure the demand of high quality, high efficiency and large quantities, mainly because the processing needs to go through multiple processes, such as: hot and cold processing process, cutting process and quenching process, etc., so as to produce high-quality self-aligning roller bearings.
