ABSTRACT:
The bearing assembly for supporting one end of a rotatable shaft, such as the lower end of an agitator drive shaft inside a mixing tank, includes a mounting sleeve surrounded and spaced radially outwardly from the lower end of the drive shaft, a support supporting the mounting sleeve at a location where there is sufficient space between the mounting sleeve and the tank bottom to gain access to the lower end of the drive shaft, an annular bearing slidably mounted on the drive shaft, a bearing housing disposed inside the mounting sleeve and receiving the bearing to provide a bearing/bearing housing subassembly and a locking arrangement on the bearing housing and the mounting sleeve. The locking arrangement permits movement of the bearing/bearing housing subassembly between a locked position where it can be moved longitudinally relative to the drive shaft into and out of the mounting sleeve and a locked position inside the mounting sleeve where the bearing housing is restrained against longitudinal movement relative to the drive shaft. When in the unlocked position, the bearing/bearing housing assembly can be withdrawn from the mounting sleeve and completely off the end of the drive shaft and moved away from the shaft through the space between the mounting sleeve and the tank bottom wall.
