1. An improved bearing assembly comprising:
- (a) a bearing housing defining a shaft bore containing therein at least one bearing, said bearing adapted to rotatably support a shaft extending into said shaft bore;
(b) said housing further defining a receiving bore extending from a first location at an exterior surface of said housing towards said shaft bore to a second location radially inward of said first location, said receiving bore terminating prior to intersecting with said shaft bore to define a temperature measurement surface therein;
(c) a thermocouple, said thermocouple including dissimilar wires connected at a measuring junction, said measure injunction of said thermocouple being embedded in said receiving bore and located adjacent said temperature measurement surface so as to be responsive to the temperature within said housing; and
(d) a signal transmitter located proximate said housing for transmitting the signals received from the measuring junction to an instrument for determining the temperature sensed by the thermocouple at the measuring junction.

Abstract
A bearing assembly with a temperature measuring device embedded in the housing and arranged so as to be responsive to the temperature within the housing. The bearing assembly includes a transmitter for transmitting the signal received from the measuring or sensing junction of the temperature measuring device to an instrument for determining the temperature sensed by the device.
