Today, the editor will explain to you: the five basic characteristics of spherical roller bearings. For spherical 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 resistance, high wear resistance, contact fatigue strength, and processing procedures are also first-class. These conditions are the basic performance of spherical roller bearings.
1. When using a spherical roller bearing, the hardness of the bearing is one of the key points of the entire bearing quality. In the process of use, the hardness of the bearing should reach HRC58~63 in general, so as to better achieve the expected effect. In addition, it has a large elastic buffer in terms of high-strength contact fatigue and wear resistance.
2. In order to prevent the bearing from rusting when using the bearing, especially when the bearing parts and finished products are processed or stored, bearing steel with high rust resistance should be selected.
3. When using spherical roller bearings, one of the things that is often a headache is the wear resistance of the bearing, and wear resistance is also a question often asked by users when purchasing bearings, which is mainly due to the bearing ring, rolling Rolling friction and sliding friction often occur between the body and the cage during use, and such friction, as mentioned at the beginning, cannot achieve the expected effect due to the unstable wear resistance of the bearing. The damage caused must be made in the selection of bearing steel, and the one with strong wear resistance should be selected.
4. Why do you want to improve the service life of spherical roller bearings? Mainly because in the process of use: the bearing will easily cause damage after contact with the contact surface under the action of cyclic load, and even cause cracking and spalling. Roller bearings should be selected with strong contact fatigue, so as to effectively prolong the bearing life.
5. In addition to the above-mentioned requirements, the processing performance of spherical roller bearings must be strictly controlled, which is also to ensure high quality, high efficiency and large-scale requirements, mainly due to the need to go through multiple processes during processing, such as : Hot and cold processing, cutting and quenching processes must be controlled in order to produce high-quality spherical roller bearings.
