An isolator to prevent transmitted vibrations includes a ring which fits within a shaft opening of a housing. A bearing is received within the isolator and a shaft is received within the bearing. The vibrations are decoupled from a vibration transmission path by the different material of the isolator. The isolator is preferably manufactured of a rigid laminate material dissimilar to the housing material. Another embodiment of the present invention integrates the isolator directly into the bearing assembly. By manufacturing the outer member of the bearing assembly of the laminated material, the outer member similarly breaks the transmission path of vibrations without the need of the additional member. Noise is thereby substantially prevented from reaching, and from being amplified by, the housing. This greatly reduces the resulting noise and vibration.
