Insert bearing is actually a variant of deep groove ball bearing, characterized by its spherical outer diameter surface that can fit into a corresponding concave insert bearing self-aligning role to play within.
Although its basic properties and deep groove ball bearings should be similar, but because of this bearing most of the machinery used in the rough, the installation location is not precise enough, the shaft and the seat of the neutral axis of the hole deviation, or the long axis of the deflection and large cases, but not high enough precision bearing itself, some structures are relatively rough, so compare the actual performance of the same performance specifications of deep groove ball bearing play on a considerable discount. For example: with the top wire of the insert bearings used in large stiffness difference deflection through shaft, the bearings with seals on both sides, can be tight to prevent dirt intrusion, Pat factory filled with the right amount of lubricant before installation without cleaning , no additional lubricant, bearing inner ring on the top end protruding wire when tightening the screws on the shaft. Permissible axial load should not exceed 20% of the rated dynamic load.
With eccentric outer insert bearings and with the top wire of the insert bearing performance is basically the same, but not on the top wire on the inner ring, but in the eccentric sleeve. Tapered bore insert bearings with 1:12 tapered bore tapered bore, can be installed directly on the tapered shaft, or with the adapter installed in the shaft shoulder axis, and can fine-tune the bearing clearance.
insert bearing priority for applications that require equipment and spare parts for simple cases, such as for agricultural machinery, transportation systems or construction machinery. Mainly used to bear radial load mainly radial and axial joint load, generally should not alone bear the axial load, such bearings can be installed separately inner ring (with a whole group of roller and cage) and the outer ring. This kind of bearing does not allow a tilt axis relative to the housing, the radial load appointments will produce additional axial force. This kind of bearing axial clearance of the size of the bearing can work in large, when the axial clearance is too small, the higher temperature; axial clearance is large, bearing easily damaged. Therefore, in the installation and operation of special attention to adjust the bearing axial clearance, if necessary, preloaded mounting, in order to increase the rigidity of the bearing.
Insert bearings with housing are the bearings and bearing binds together a bearing unit. Most of the outer insert bearings are made of spherical, and with a insert bearing bore installed together, the structure forms, versatility and interchangeability.
