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 for centering. The outer spherical bearing with a seat is a bearing unit that combines the rolling bearing and the bearing seat. Most outer spherical bearings make the outer diameter spherical and install it together with the bearing seat with a spherical inner hole. The structure is diverse, with good universality and interchangeability.
At the same time, this type of bearing also has a certain degree of centering in design, is easy to install, and has a dual structure sealing device, which can work in harsh environments. Outer spherical bearings are preferred for applications that require simple equipment and components, such as agricultural machinery, transportation systems, or construction machinery.
Main features: maintenance free design/lifelong maintenance without oil injection/more effective sand and dust prevention.
