An insert bearing with housing is a bearing unit that combines a rolling bearing with a bearing housing. Most of the outer spherical bearings are made of spherical surfaces and are mounted together with imported bearing housings with spherical inner holes. The structure is diverse, versatile and interchangeable. At the same time, these bearings are also designed with a certain degree of self-alignment, easy to install, and have a double-structured sealing device that can work in harsh environments. The bearing housing is typically cast.
