Outside ball bearings

Outside ball bearings bearing consists of both sides with a sealed spherical ball bearings and cast (or steel stamping). Same spherical ball bearings and deep groove ball bearings inside the structure, but such a bearing inner ring is wider than the outer ring outer ring has a truncated spherical outer surface and a concave spherical bearing to match the self-aligning. There is a gap between the hole and the shaft is usually such a slim ball bearing, with the top wire, heart, sets tight sets or the bearing inner ring is fixed to the shaft, and rotate with the shaft.
Structural features
Spherical ball bearing is actually a variant of deep groove ball bearings, INA bearings is characterized by its outer diameter surface of the sphere, you can play with the corresponding inner concave spherical bearing self-aligning effect. Although its basic properties and deep groove ball bearings should be similar, but because most of the bearings used in the rough machine, the installation location is not precise enough, the axis of the shaft and housing bore neutral difference, or the long axis deflection like the case of large, and the precision of the bearings themselves is not high enough, some structure is relatively rough, so the actual performance of the performance specifications of the deep groove ball bearings the same play a considerable discount.
Spherical ball bearings with the top wire is applied to large stiffness difference deflection through shaft, the self aligning ball bearings with seals on both sides, can be tight to prevent dirt intrusion, had filled the right amount of lubricant at the factory before installation without cleaning, not require additional lubricant, the top end of the wire protruding screws on the bearing inner ring on the shaft tightened. Permissible axial load should not exceed 20% dynamic load rating.
With eccentric outer spherical ball bearings and spherical bearings performance with the top wire of the same, only the top wire is not on the inner ring, but in the eccentric sleeve. Bore tapered bore spherical ball bearings with 1:12 tapered bore taper, can be installed directly on the tapered shaft, or by means of an adapter bushing is mounted on the optical axis without shaft shoulder, and fine-tune the bearing clearance.
The use of spherical bearings
Spherical bearing the same internal structure and deep groove ball bearings, but this is wider than the outer ring of the ball and roller combined bearing

 inner ring, an outer ring has a spherical outer surface and a concave spherical bearing to match the self-aligning, compact, easy handling, supported using simple, commonly used in mining, metallurgy, textiles, transportation machinery.
