A bearing unit with a seat is a bearing unit that integrates an outer spherical bearing with a bearing seat. Most outer spherical bearings are processed into spherical structures, which can be matched and assembled with bearing seats with spherical inner holes. The structural styles are diverse and have good universality and interchangeability.
This type of bearing structure comes with self centering ability, easy assembly operation, and is equipped with a double-layer sealing structure, which can be used in environments with poor working conditions. The bearing seat is mainly divided into two manufacturing processes: casting and stamping.
