Recently we examined how brinelling contributes to bearing failure. Now we’ll examine bearing smearing. Just a reminder: Factors that contribute to bearing failure include material fatigue; operating with a heavier loading than specified; inadequate or unsuitable lubrication; careless handling; poor sealing; and bearing balls or rollers installed too tightly, with insufficient internal bearing clearance. Each of these contributors leaves […]
Linear bearings
Mechanical wear — How bearings fail Part 1 of 6
Today, bearing manufacturers can reliably predict the operating life of bearings, which makes it easier to specify the right bearing for an application. Bearings do fail, if for no other reason than components do not operate forever. A number of causes contribute to failure, including material fatigue; operating with a heavier loading than specified; inadequate or […]
