Roller and Ball Bearings
Today’s improved materials provide greater reliability of bearings in use. High temperature materials are available for bearing fabrication, but the practical limit is really determined by the breakdown temperature of the lubricant. Synthetic lubricants are commonly used in high temperature applications. Bearing load ratings are established on the results of laboratory rolling contact fatigue tests. Real world conditions such as misalignment, vibration, shock loading, insufficient or inefficient lubrication, extremes of temperature, or contamination, will decrease the life expectancy of the bearings. If these conditions are severe, they may lead to premature failure of the bearings. Some common characteristics of bearing failures are listed below:
Some of the factors that may lead to bearing failure are improper lubrication, impact loading, vibration, excess temperature, contamination, excessive loading, and misalignment. AMC can provide failure analysis services to determine the cause of your bearing failure. Contact Information
