Rotating equipment, either in storage, or down for long periods of time, should be rotated on a regular basis. This prevents two things: rust forming in the bearings, gears, etc., due to lubricant settling into the reservoir. false brinelling, which is micro-spalling of the bearing raceways due to impacting. This occurs when vibration is present…

Co-author, Stan Riddle. Lubricating bearings on a regular PM schedule has some inherent problems-mainly, how do you know if a bearing needs lubricating or not? If the bearing seal is not compromised, grease should stay in the bearing, and provide lubrication for a long time. But if the seal is blown, the bearing will require…

At a recent Fixturlaser Smart Machine Checker (SMC) training class, one particular pump came up during the discussions. This pump has been “a problem child” for years. It had been rebuilt recently by one of the class attendees. The mechanic had rebuilt the pump “just as it had come apart” and was certain the impeller…

The Fixturlaser Smart Machine Checker (SMC) is a great mechanic’s tool, for evaluating the overall health of rotating machinery. But did you know it’s also a lubrication tool for greasing bearings? Let me explain. One of the vibration measurements in the SMC is called Bearing Defect Factor. The Bearing Defect Factor is a measurement of…
