The outer spherical ball bearing is actually a variant of the deep groove ball bearing, characterized by its outer ring outer diameter surface being spherical, which can be matched into the corresponding concave spherical surface of the bearing seat to play a centering role.
Although its basic performance should be similar to that of deep groove ball bearings, due to the fact that this type of bearing is mostly used in relatively rough machinery, the installation and positioning are not precise enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and has large deflection, and the accuracy of the bearing itself is not high enough. Some structures are also relatively rough, so the actual performance of deep groove ball bearings with the same specifications should be given a considerable discount.
Materials - Ferrules are typically made of corrosion-resistant alloy steel, mixed with ceramic (silicon nitride) balls, and can be used for high-speed or demanding applications.
Sealing ring - A sealing ring can be installed in areas that prevent contamination or require lifelong lubrication.
Contact angle - HQW angular contact ball bearings have different contact angles
Pre load - Bearings can be pre tightened in a back-to-back (DB), face-to-face (DF), or series (DT) manner according to application requirements. We also offer * * bearings that can be paired in any way.
Tolerance - If required, HQW micro bearings can meet ABEC9 (ISO P2) standards.
