ABSTRACT:
Bearing assembly including at least one proximity probe for monitoring the relative vibration of a rotating shaft contained therein. The bearing assembly includes a bearing housing surrounding and supporting a cylindrical shell. The cylindrical shell defines a shaft bore for receiving a rotating shaft. At least one proximity probe is embedded in the cylindrical shell for monitoring the shaft vibration. A second proximity probe may be added to enable monitoring radial shaft position. The proximity probes are connected to an instrument or instruments for displaying a signal received from the probes for allowing a user to determine shaft vibration or position.
