Insert ball bearings is in fact a variant of deep groove ball bearing, is characterized by its outer ring outside diameter surface is spherical, can be mixed in to the concave spherical surface bearing the appropriate role of spherical.
Although it of basic performance and deep groove ball bearing should is similar of, but due to this bearing most application in comparison rough of machinery in the, installed positioning enough accurate, axis and seat hole of axis on neutral difference, or axis long and deflection large, of situation Xia, and bearing itself precision also enough high, some structure also more rough, so total performance of actual performance comparison same specifications of deep groove ball bearing to playing Shang is of discount. For example with wire insert ball bearing stiffness difference of applied deflections through shaft, the bearings with seals on both sides, tight dirt intrusion prevention, the factory has filled appropriate amount of lubricant, do not need cleaning before installation, without additional lubricant, bearing inner rings on the convex side of the top screws when you tighten the shaft and solid. Allows dynamic axial load should not exceed the rated load of 20%.
Insert ball bearings with eccentric and spherical bearings with top performance is basically the same, just not on the inner ring, but rather on the eccentric sleeve. Insert ball bearings with a tapered bore taper of the tapered bore hole with 1:12, may be mounted directly on tapered shaft, or make use of adapter bushings installed in the shaft on the optical axis, and fine tune the bearing clearance.
