Amplitude Demodulation for Condition Monitoring of Bearings
June 2, 2019Far from straightforward, it’s not easy to track bearing damage. As one effective defect localizing solution, engineers use condition-based monitoring technology to monitor particular performance-biased subsets. Then, by applying some form of amplitude demodulation assessment, the condition monitoring techniques reveal behavioural information about a chosen bearing’s functions. Of some problem here, this is a mathematically […]

Common Causes and Remedies for Roller Bearing Overheating
May 15, 2019This post is intended as a guide to roller bearing overheating causes. One easy enough causative factor to spot would be a low lubrication level. There’s no oily film between the rollers, so the fast-moving bearing components generate heat as they rub against one another. It’s a pity that every overheating gremlin can’t be picked […]

What is Rolling Contact Fatigue in Bearings?
April 30, 2019Rolling point fatigue, as the term implies, occurs as a consequence of point contact stress. With these focal points rubbing together, material wear is inevitable. The hardness-to-malleability coefficient of the bearing alloy counteracts the effect, at least as much as is possible, but there comes a moment when those stress-focusing contact regions can no longer […]

Understanding What Limiting Speed of Bearings is All About
April 16, 2019Equipment shafts, they can only go so fast. Beyond that point, the rolling elements on each shaft end start to cook. It seems like the laws of physics have something to say about an out-of-control rotating bearing. Bound by those laws, a speed and its additional friction causes a subsequent increase in operational heat. Left […]

What are White Etching Cracks in Roller Bearings?
April 2, 2019Appearing as pale hairline fissures, white etching marks emerge on bearing surfaces when application stress conditions exert heavy kinetic energies. The true material defect is hidden inside the alloy, so the etching cracks are the tip of the proverbial iceberg here. They’re a sign of a deeper issue. There are no two ways about it, […]
