Bearing noise can be generated by several factors which can cause premature failure. Most failures he has seen coming into a repair shop is from LACK of proper lubrication. Most people would think electrical but not so. Another noise generated can be from improper alignment, belts too loose or too tight. All belts should have the proper tension. He has found in some cases a customer replaced 4 out of 5 belts. The 4 new belts were tight of course but the 5th one flopped around the pulley. With the increase of variable speed drives you may find excess current on the motor shaft which could cause bearing noise and premature failure. Over lubrication could be a problem with a motor as well. One of the things to look for is an increase in the motor amp draw. All these problems cause resistance which increases the amperage.
Split bearings are bearings that go on the shaft in halves. Most are Babbitt bearings and used for heavy slow speed motors. Usually the rotor is very heavy so that is the reason for the split. Another reason is that the bearing can be taken out in halves without taking the end bell completely apart. That saves a lot of downtime in an emergency situation. Here again the main factors are lubrication, alignment and temperature. Either one could end the life of a motor.
He has demonstrated over and over his consulting skills each time he has called on his accounts. He has maintained accounts for years with multi-million dollar volume. This requires him to constantly find out what his customers problems are and provide solutions and cost effective repairs, be aware of who his competition is so he does not lose business.
