1 Load size, direction and properties Ball bearings are suitable for light loads and roller bearings are suitable for heavy loads and shock loads. When the Rolling Bearing is subject to pure axial load, the Thrust Bearing is generally selected; when the rolling bearing is subjected to pure radial load, a deep groove ball bearing or a short cylindrical roller bearing is generally selected; when the rolling bearing is subjected to pure radial load, there is not much For axial loads, Deep Groove Ball Bearings, angular contact ball bearings, Tapered Roller Bearings, self-aligning balls or self-aligning roller bearings can be used; when the axial load is large, angular contact with a large contact angle can be used. Ball bearings and tapered roller bearings, or combinations of radial bearings and thrust bearings, are particularly suitable when extremely high axial loads or particularly axial stiffness are required.
2 The allowable speed varies greatly depending on the type of bearing. In general, bearings with low friction and low heat are suitable for high speeds. When designing, the rolling bearing should work under the condition of its limit rotation speed.
3 When the rigid bearing is under load, elastic deformation occurs at the contact portion between the Bearing Ring and the rolling element, and the deformation amount is proportional to the load, and the ratio determines the rigidity of the bearing. Generally, the rigidity of the bearing can be increased by the pre-tightening of the bearing; in addition, in the bearing support design, considering the combination and arrangement of the bearings, the bearing support rigidity can also be improved.
4 Self-aligning performance and installation error After the bearing is installed in the working position, the installation and positioning defects are often caused due to manufacturing errors. At this time often due to the shaft yield and thermal expansion and other reasons, the bearing is subjected to excessive load, causing early damage. Self-Aligning Bearings can overcome the defects caused by mounting errors on their own and are therefore suitable bearings for such applications.
5 installation and disassembly of tapered roller bearings, Needle Roller Bearings, etc., belonging to the inner and outer rings can be separated bearing type (the so-called separate bearings), easy installation and removal.
6 Marketability Even if the horizontal lathes are included in the catalogue, the market may not have sales. On the contrary, some of the bearings that are not listed in the catalogue are mass-produced. Therefore, it should be clear whether the bearings used are readily available.
There are various types of rolling bearings. When selecting them, the following factors can be considered for selection.
