ABSTRACT:
The present invention provides a bearing assembly for use in a display assembly having a plurality of louvers which rotate in synchronism with each other and, in doing, displays different advertising messages. The bearing assembly includes a housing having an axis and a shaft extending axially through the housing. A pair of axially spaced bearings rotatably mount the shaft to the housing. A pair of collars are secured to the shaft so that the bearings are contained in between the collars while a Belleville washer is sandwiched between one collar and one bearing and exerts a compressive force on the bearings and a tension force on the shaft in order to compensate for bearing wear and manufacturing tolerances. A seal is secured to and rotates with the shaft. The seal includes an outer annular lip which extends over one end of the bearing housing to prevent contaminants from entering the bearing housing.
