Classed as rolling contact devices, anti-friction bearings operate on a well-recognized principle. Their rolling elements are in contact with one another. Set in motion, the lubricated rollers power along, and between, two rings while locked inside a caging mechanism. For hydrodynamic bearings, a whole other process is taking place. Instead of a group of solid […]
Generally, the inner ring of a rotating bearing locks tightly against a shaft so that the two mechanical parts can spin as one. In order to accommodate this operation, massive amounts of pressure force a slightly smaller ring opening onto a slightly larger shaft circumference. That’s how press fit fastening works. Regrettably, this high-tolerance press […]
Rolling elements, just like human beings, are expected to handle stress. Now, people do succeed in dealing with such pressures, at least to some degree or other. For bearings, it’s a little harder. They can’t adapt, not easily. No, to properly deal with load-induced stress, their carrying capacity should be determined before they’re pressed into […]
Here’s a tough mandate to solve. In an industrial setting, a set of bearings can be porous and packed with grease. Shifting this scenario so that the mountings are situated inside a food-grade equipment frame, those normally beneficial features assume application-deleterious proportions. The regulations protecting the equipment can’t permit just any old grease type, nor […]
Far 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 […]
