Abstract
A bearing including a wearable section including a wear sensor is provided. The bushing includes a wear sensor that provides feedback to a user relating to the amount of useable life of the bearing that has been used. The sensor may be in the form of a wire imbedded in the wearable section of the bearing such that as the wearable section wears over time, the wire may be worn through breaking a circuit including the wire. An indicator module can sense the breakage of the wire and determine the amount of useable life of the bearing that has been used. In one implementation, the bearing is used in a drying drum. In one form of the invention, a method of monitoring wear of the bearing is provided that includes monitoring changes in electrical properties of a sensor mounted in the bearing.
