spherical radial ball bearing

タイトルまたは説明

spherical radial ball bearing:

Outer spherical ball bearing deep groove ball bearing is actually a variant, is characterized by its outer diameter surface of the sphere, can be allocated into the corresponding concave spherical bearing in mind the role played tune.

Although its basic properties and deep groove ball bearing is similar, but because most of these bearings used in rough machinery, installation and positioning is not accurate enough, shaft and hole axis on the neutral difference, or axial length and large deflection and other conditions, and the bearing precision is not high, some the structure is also more rough, so the performance of actual performance compared to the same specifications of deep groove ball bearings to make considerable discount.For example: silk top with the outer spherical ball bearing used in poor stiffness deflection through shaft, with both sides of this bearing ring, can prevent dirt intrusion, the factory had filled with just the right amount of lubricant, before installation without cleaning, do not need to add lubricant, the bearing inner ring projecting end top screw at shaft fastening. Allow axial load shall not exceed the rated dynamic load *0%.

Eccentric sleeve with the outer spherical ball bearings with outer silk top with spherical bearing performance is basically the same, but not inner wire on top, but in the eccentric sleeve.Taper hole of outer spherical ball bearing inner hole with 1:*2 taper for the tapered hole, can be directly installed on the cone axis, or with tight bushing set installed in the non-axis optical axis on the shoulders, and fine-tune bearing clearance.

Outside the spherical bearing is applied to the requirements of equipment and spare parts in simple situations, such as for agricultural machinery, transport system or building machinery.

Mainly used to bear radial and axial joint loads, the general should not be alone to bear the axial load, the bearing can be mounted separately inner ring (with a full group of roller and the retai
