Stainless steel bearing unit is a kind of bearing unit that combines rolling bearing and bearing housing. Most stainless steel outer spherical bearings have a spherical outer diameter and are installed together with bearing housing with a spherical inner hole. The structure is diverse, versatile and interchangeable.
Although its basic performance is similar to that of deep groove ball bearing, most of the bearings are used in relatively rough machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole is neutral, or the shaft is long and the deflection is large, and the accuracy of the bearing itself is not high enough, and some structures are relatively rough, so the actual performance of the bearing is relatively the same specification Deep groove ball bearings are subject to considerable discount.
The insert ball bearing is a variant of the deep groove ball bearing. the outer diameter surface of the outer ring is spherical, which can be fitted into the corresponding concave spherical surface of the bearing housing to play the role of centering. The insert ball bearing is mainly used to bear the combined radial and axial load, which is mainly the radial load. Generally, it is not suitable to bear the axial load alone
