The outer spherical ball bearing is a variant of the deep groove ball bearing in practice; its characteristic is that the outer diameter of the outer ring is spherical; it can be fitted into the corresponding concave spherical surface of the bearing seat to achieve the effect of self-aligning.
Although its fundamental function should be similar to that of deep groove ball bearings; however, most of these bearings are used in relatively rough machines; the positioning of the device is not accurate; the axis of the shaft and the hole is poorly centered; or the axis is long and the deflection is In the case of a large class; and the accuracy of the bearing itself is not high; some layouts are also rough; therefore, the practice of the common function reflects the same standard deep groove ball bearing to be equipped with a suitable buckle. For example, the outer spherical ball with the top wire The bearing is applied to the through shaft with large difference of rigidity and deflection; the bearing has sealing ring on both sides; it can avoid the intrusion of dirt tightly; the excess lubricant is filled when leaving the factory; there is no need to remove the device before the device; no need to add lubricant; bearing The top wire screw on the projecting end of the inner ring is fastened on the shaft. The axial load of the promise shall not exceed 20% of the additional dynamic load.
The outer spherical ball bearing with the partial pain sleeve has the same function as the outer spherical bearing with the top wire; only the top wire is not on the inner ring; instead, it is on the partial pain sleeve. The inner hole of the tapered spherical outer spherical ball bearing is the belt 1: 12-cone tapered bore; can be mounted directly on the tapered shaft; or with a tight bushing on the shaft without the shoulder; fine-tuning the bearing clearance.
