Abstract
A bearing system that includes a bearing supported in a flexible bearing bracket, for example for use in fractional horsepower shaded pole type electric motors. The bearing system is self aligning, the bracket being able to deflect to compensate for deviations in the radial alignment of the rotor shaft. A rotation lock restrains the bearing against rotation within the bracket. In the preferred embodiment the bracket is composed of an elastomer and the bearing is composed of a high performance plastic polymer, so that the bearing system is non-lubricating.
