This 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 […]
Rolling 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 […]
Equipment 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 […]
Appearing 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, […]
As detailed previously, bearing brinelling is an indentation effect that occurs when the elastic limits of a product’s race surfaces are surpassed. The balls push against the hard steel ring, and the spheroids create dents. Knowledge is power, as they say, so surely this particular nugget of information must be of help as a dent […]
