What is concentricity?

Question

Accepted Answer

Concentricity refers to the condition where two or more objects share the same center point.

Concentricity is a geometric property that describes the relationship between multiple objects.
It means that the objects have a common center point.
In engineering, concentricity is often used to ensure accurate alignment and positioning of components.
For example, in a rotating shaft and bearing assembly, the shaft and the inner race of the bearing should be concentric to minimize vibration and ensure smooth operation.
Concentricity can be measured using specialized tools such as concentricity gauges or coordinate measuring machines.
