1. A bearing assembly for a rotor, said bearing assembly comprising:
- an inner race;
an outer race;
a plurality of rolling elements positioned between said inner and outer race; and
at least three sensor assemblies coupled to a first side of said outer race, and at least three sensor assemblies coupled to an opposite second side of said outer race such that said sensor assemblies are approximately-equally spaced about an outer periphery of said outer race first and second sides, each of said sensor assemblies comprising at least one temperature sensor and at least one acoustic sensor.

Abstract
A method for predicting bearing failure, wherein the bearing includes an inner race, an outer race, and a plurality of rolling elements between the inner and outer race. The method includes coupling a sensor assembly to the outer race, the sensor assembly including at least one temperature sensor and at least one acoustic sensor, generating a bearing performance model based on an initial signal received from the sensor assembly, receiving a second signal from the sensor assembly, and comparing the second signal to the bearing performance model to predict a bearing failure.
