Controlling maintenance and repair costs in a facility has always been a challenge for maintenance and reliability professionals. In today's environment, controlling costs has become critical in helping to remain competitive in your respective industry and operating an efficient facility. Improving condition monitoring and predictive maintenance techniques and procedures can go a long way in increasing asset availability and reducing unplanned downtime, thus greatly reducing costs associated with operating in a reactive maintenance mode.Lubrication related bearing failures seem to always be one of the major challenges in any plant and facility. The costs associated when machines fail and production ceases can be damaging to the bottom line of even the most profitable company. Identifying potential failures before they become catastrophic has become the new standard for maintenance and reliability departments worldwide. Facilities that continue to operate reactively, and without utilizing predictive maintenance tools often find themselves behind their competition and always in "firefighting" mode. One technology in particular can easily be implemented into an existing maintenance and reliability program. Airborne and structure-borne ultrasound is an easy to use technology and can be applied to many different energy conservation and equipment reliability applications. This paper will discuss the benefits of utilizing airborne and structure-borne ultrasound to reduce bearing failures due to over and under lubrication conditions.
