Outer spherical ball bearing is deep groove ball bearings in the practice of a form, characteristic is its outer diameter for spherical surface of sliding bearing, can match into the corresponding concave spherical bearing self-aligning effect.
Despite its fundamental functions and deep groove ball bearings should be similar, but because the bearings are mostly applied in composite bearing compared rough mechanical device positioning not accurate, the axis of the shaft with a hole to neutral, or under the condition of large axial length and deflection etc, and the bearing itself precision is not high also, some structure is rough, and the function of the practice embodies contrast gauge same case of deep groove ball bearings to the appropriate discount.Insert ball bearing units, for example, with the top wire is applied to the stiffness difference deflection of shaft, this kind of bearing with seals on both sides, can avoid dirt intrusion, closely when they leave the third loading amount of slip agent, before the device does not need to clean, do not need to add lubricant, bearing inner ring protruding the top wire screw fastening the shaft on the side. The promised to axial load may not exceed 20% of the additional dynamic load.
With eccentricity of outer spherical ball bearing outer spherical bearing with top silk and function as fundamental, on top of silk, not only, but on the offset sets.Cone hole of outer spherical ball bearing inner hole for belt 1:12 taper cone hole, the device can be directly on the conical shaft, or with the aid of adapter bushing device without shoulder axis, and fine-tune the bearing clearance.
