Recently we examined how surface distress contributes to bearing failure. Now we’ll examine corrosion. Corrosion occurs primarily when either lubricants fail or the seals have failed and the bearings have been exposed to water or corrosive liquids. Corrosion can lead to early fatigue failures through the rust that forms in the bearing, especially if rust occurs in […]
Recently we examined how smearing contributes to bearing failure. Now we’ll examine surface distress. Even with the best of manufacturing methods, no surface is perfectly smooth. In bearings, proper lubrication helps smooth out the roughness between bearings and raceways and other parts that interact. If the amount of lubrication is insufficient, or the lubricant is reaching the […]
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 […]
Recently we examined how wear contributes to bearing failure. Now we’ll examine indentations, sometimes referred to as brinelling. Just a reminder, there are a number of causes that contribute to brinelling, including: • Material fatigue • Operating with a heavier loading than specified • Inadequate or unsuitable lubrication • Careless handling • Poor sealing • Bearing balls […]
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 […]
Designed primarily to showcase mechanical motion during a trade show, this new kinetic gear sculpture from SDP/SI illustrates mechanical motion principles. It was designed and arranged by Andrea Davide, a New York-based artist who specializes in creating unique metal sculptures. Check out the video; this is a good way to show mechanical motion principles, whether […]
In this episode Miles looks at the two most common motors used in motion control operations.
In this episode Miles looks at the basics of motion controllers and motion profiles.
