Abstract
An agitator having a hollow spindle housing with first and second ends, and one or more agitating devices projecting from the spindle housing. A first bearing retainer holds the first end of the spindle housing and a first race of a first bearing, and a second bearing retainer holds the second end of the spindle housing and a first race of a second bearing. A first agitator mount holds a second race of the first bearing, and a second agitator mount holds a second race of the second bearing. A rigid inner support may be located inside the spindle housing and connect the first and second bearing retainers together to hold the first races of the first and second bearings in axial alignment. The spindle housing may have sound reducing members to reduce the amplitude of human-audible sounds generated by the agitator.
