Do you really know the bearing you are using

  Bearings generally consist of inner rings, outer rings, rolling elements and cages. For sealed bearings, add lubricant and seals (or dust caps). This is what the bearing is all about.

  According to the working conditions of the bearing, different types of bearings can be selected to better exert the function of the bearing and prolong the service life of the bearing. We need to consider the following factors when selecting bearings:

1. Radial load 2. Axial load 3. Speed requirement 4. Radial runout

5. Axial runout 6. Operating temperature 7. Noise requirements 8. Lubrication condition

  Bearing models generally have a pre-code, a basic code and a post-code. Under normal circumstances, the bearing model is only represented by the basic model. The basic model generally contains three parts, type code, size code and inner diameter code. The post-code is to use letters and numbers to indicate the structure, tolerance and special requirements of materials of the bearing. The prefix code is used to indicate the sub-components of the bearing, which are represented by letters.General bearing (rolling bearing) code method, divided into: front code, basic code and post code.

  The market requirements of various mechanical devices and instruments using rolling bearings are becoming more and more stringent, and the conditions and performance required for bearings are also becoming more and more diverse. In order to select the most suitable bearing from a large number of structures and dimensions, it is necessary to study from various angles. When selecting a bearing, generally, the bearing structure is roughly determined by considering the arrangement of the bearing as a shaft system, the difficulty of installation and disassembly, the space allowed by the bearing, the size and the marketability of the bearing. Next, while comparing and studying the design life of various machines using the bearing and the various durability limits of the bearing, the bearing size is determined. When selecting a bearing, it is often biased to consider only the fatigue life of the bearing, and the grease life, wear, noise, etc. caused by the aging of the grease also need to be fully studied. Furthermore, according to different uses, it is necessary to select specially designed bearings for accuracy, clearance, cage structure, grease, etc. However, there is no certain order and rules for the selection of bearings. The priority should be given to the conditions, performance and most related matters required for the bearing, which is especially practical.
