NSK outer spherical bearing ball bearing is in fact a variant of deep groove ball bearing, which is characterized by the surface of the outer diameter of its outer ring as a spherical surface, which can fit into the concave spherical surface of the bearing seat and play the role of the center. Although its basic performance and deep groove ball bearings should be similar, but because the bearings are mostly used in relatively rough machinery, the installation is not accurate, the axis of the axis and the axis of the seat are neutral, or the axis is long and the deflection is large, and the precision of the bearing itself is not high, and some of the structure is relatively rough. Therefore, the actual performance of the deep groove ball bearings with the same specifications should be fairly discounted. For example, the NSK spherical ball bearing with top wire is applied to a general shaft with a large rigidity, which can strictly prevent the invasion of the dirt, and can fill a proper amount of lubricants in the factory. It does not need to be cleaned before installation, no lubricant is needed, and the top wire screw on the convex end of the bearing inner ring is fastened to the shaft. The axial load shall not exceed 20% of the rated dynamic load. The outer spherical ball bearing with eccentric sleeve is basically the same as the outer ball bearing with top wire, but the top wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the spherical spherical ball bearing of the cone hole is a conical hole with the 1:12 taper. It can be installed directly on the cone axis, or is installed on the shafts of the non shafts with the help of the tightened bushing, and can adjust the clearance of the bearing. It is mainly used to bear radial and axial joint loads based on radial load. It is not suitable for axial load alone. This kind of bearing can be installed in the inner ring (with all the rollers and maintainers) and the outer ring. The bearing does not allow the shaft to tilt relative to the housing, and additional axial forces are generated when the radial load is applied. The size of the axial clearance of this kind of bearing has a great relationship with the normal work of the bearing. When the axial clearance is too small, Wen Sheng is high. When the axial clearance is large, the bearing is easily damaged. Therefore, during installation and operation, special attention should be paid to adjusting the axial clearance of bearings, and when necessary, pre interference can be installed to increase the rigidity of bearings.
NSK outer spherical bearing product features: the outer ring of the outer spherical bearing bearing has a spherical outer diameter, which is matched with the inner hole of the concave spherical surface of the bearing seat, and has the function of automatic heart adjustment. It is suitable for the shaft with poor rigidity and greater disturbance. The bearing has two sealing rings on both sides, which can prevent dirt from penetrating. A suitable amount of lubricant has been installed at the factory. No cleaning is necessary before installation. No lubricant is required during the permitted lubrication period. The axial load of the top screw on the protrusion end of the bearing inner ring is less than 20% of the rated dynamic load when it is strong on the shaft.
NSK external spherical bearings use: the outer spherical bearing is preferable to the simple situations requiring equipment and parts, such as in agricultural machinery, transportation systems, or construction machinery.
