18 Ultrasound: Critical Component to Reliability Centered Lubrication Adrian Messer, CMRP Keeping a handle on lubrication is easy, right? All one needs to do is make sure the right lubricant is used in the right amount and at the right time. If only it were that simple... I t's estimated that 60 to 90 percent of all bearing failures are lubrication-related. Bearing failures often lead to unplanned and costly downtime that impacts production and affects all related components around the bearing. While the cost varies by incident and plant, it can add up. Since the most common cause of bearing failure is lubrication-related, it's easy to see lubrication is serious business. For the longest time, that "serious business" has been conducted in a way that on the surface makes perfect sense-but actually borders on haphazard. Many technicians rely on "preventive" time-based lubrication alone. That is, every X number of months the grease gun comes out and the bearings are lubricated. After all, under-lubrication can be detrimental, causing equipment failure, costly repairs and replacements, significant unplanned downtime and lost profit. However, by relying solely on time-based lubrication or a combination of planned maintenance and temperature readings to serve as a proxy for lubrication status, one runs the risk of something just as bad, if not worse: over-lubrication. Over-lubrication has been reported both anecdotally and in presentations at various conferences to be the primary cause of premature bearing failure. Relying on time-based periodic lubrication assumes bearings need to be greased at defi ned time periods. This often evolves into a well-intentioned guessing game; adding more lubrication to a bearing that is already adequately greased is a real risk.
