ABSTRACT:
A bearing mounting arrangement is provided in which a dimension stabilizing ring is molded into a motor housing bearing cap to limit critical bearing mounting variations in the, as molded, plastic bearing cap. The dimension stabilizing ring has an inner castellated cylindrical surface forming axially parallel grooves. These grooves are filled with plastic during molding which include portions that intrude into the bearing mounting bore so that a bearing may be force fit in this bore, deforming these plastic portions. This fixes the outer race of the bearing and prevents rotation of it relative to the bearing cap of the motor housing.
