A seated outer spherical bearing is a standardized component that integrates an outer spherical bearing with a bearing seat, and belongs to the grease sealed deep groove ball bearing unit. Its outer ring adopts a spherical structure design, which can be adapted to bearing seats with spherical inner holes and has automatic centering function. It is widely used in mining, metallurgy, agricultural machinery, chemical equipment and other fields
This bearing unit is mainly composed of sealed outer spherical ball bearings combined with cast or stamped bearing seats, including 12 specifications such as vertical seats, square seats, diamond seats, etc. It is divided into three series: UC with set screws, UK with conical holes, and UEL with eccentric sleeves. Adopting a dual sealing structure and bearing seat oil nozzle design, it supports bolt direct installation and online grease filling, and adapts to the clearance of inner holes with different shaft diameters to achieve shaft fixation through top screws, eccentric sleeves or tightening sleeves . Daily maintenance requires regular inspection of accuracy, sealing, and lubrication status. If wear exceeds the standard, replacement is necessary
