"All types of bearings have different characteristics due to their different designs.Due to the variability and complexity of the specific installation site and application of the bearing, there is no fixed mode for the selection of bearing type. When selecting the bearing type to adapt to the specific installation site and application conditions of a host, it is suggested to take the following major factors into consideration.
Allow space
Mechanical design, the general first determine the shaft size, and then choose the bearing according to the shaft size.Usually, the small shaft choose ball bearing;Cylindrical roller bearings, adjustable roller bearings, tapered roller bearings (sometimes also optional ball bearings).If the radial space of the mounting part of the bearing is limited, the bearing with a small height of the radial section should be adopted.For example, needle roller bearings, some series of deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings or self-aligning roller bearings and thin-wall bearings.If the axial space of the mounting part of the bearing is limited, the bearing with smaller width size can be used.
Bearing load
Load size load size is usually the determining factor in choosing the bearing size.The bearing capacity of roller bearing is larger than that of ball bearing with the same dimension.Usually ball bearings are suitable for light or medium loads, roller bearings are suitable for bearing heavy loads.
Load mode pure radial load can choose deep groove ball bearing, cylindrical roller bearing.Thrust ball bearing and thrust cylindrical roller bearing can be used for pure axial load.Radial load and axial load (combined load), the general choice of angular contact ball bearings or tapered roller bearings.If the radial load is large and the axial load is small, the bearing person WeChat professional!Deep groove ball bearings and cylindrical roller bearings with internal and external rings are optional.If at the same time there are shaft or shell deformation and installation of the neutral poor situation, you can choose adjustable ball bearings, adjustable roller bearings.If the axial load is large and the radial load is small, the thrust angular contact ball bearing can be selected. If the four-point contact ball bearing also requires the performance of centering, the thrust centering roller bearing can be selected.
