Although the basic performance of radial insert bearings should be similar to that of deep groove ball bearing, because this kind of bearing is mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole are poorly aligned, or the shaft In the case of long and large deflection, the precision of the bearing itself is not high enough, and some structures are relatively rough, so the actual performance of the deep groove ball bearing of the same specification should be marked with a considerable discount.
For example: radial insert bearings with top wire is applied to through shafts with large stiffness difference and large deflection. This kind of bearing has sealing rings on both sides, which can strictly prevent the intrusion of dirt. It has been filled with an appropriate amount of lubricant before leaving the factory, and it does not need to be cleaned before installation. , No need to add lubricant, when the top screw on the protruding end of radial insert bearings inner ring is fastened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load.
The radial insert bearings with eccentric sleeve has basically the same performance as radial insert bearings with top wire, but the top wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered hole outer spherical ball bearing is a tapered hole with a taper of 1:12, which can be directly installed on the tapered shaft, or installed on the shoulderless optical shaft with the help of a fixed bushing, and can fine-tune the bearing clearance.
Radial insert bearings are preferably used where simple equipment and components are required, such as in agricultural machinery, transport systems or construction machinery.
Radial insert bearings are mainly used to bear the combined radial and axial loads mainly based on the radial load. Generally, it is not suitable to bear the axial load alone. This kind of bearing can be installed with the inner ring (with a full set of rollers and retainers) and outer ring. This kind of bearing does not allow the shaft to be inclined relative to the housing, and additional axial force will be generated under the radial load. The size of the axial clearance of radial insert bearings has a great relationship with whether the bearing can work normally. When the axial clearance is too small, the temperature rise will be high; when the axial clearance is large, the bearing is easily damaged. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre-interference installation can be performed to increase the rigidity of the bearing.
