Conformance to a common center.
the quality of having the same center (as circles inside one another)
The characteristic of circles or circular cylindrical surfaces of different radii having a common center.
As applied to tubular products, the center of the inside diameter is consistent with the center of the outside diameter. Welded, roll-formed tubing is inherently more concentric than seamless tubing because it is fabricated from precision rolled flat stock resulting in a more consistent wall thickness.
The permissible variation in the location of the axis (exact center) of a characteristic to the axis of another characteristic. The axis of the controlled characteristic must remain within a circular zone of a diameter equal to the concentricity limit.
The relationship of two circular features.
For a container, the shape in which various cross-sections have a common center.
When the shaft and perimeter of a roller or cylinder are on exactly the same centre.
The condition where the median points of all diametrically opposed elements of a cylinder (or a surface of revolution) are congruent with the axis of a datum feature.
The sharing of a common point or axis of two or more surfaces of shapes, such as cylinders, cones, spheres and hexagons.
A characteristic of a welded tube in which wall thickness remains consistent throughout the tube, and the inside and outside diameter centers are equivalent to one another.
A situation where a smaller circle is exactly in the center of a larger circle when measured in every direction. Valves will operate efficiently and give long service life only if the valve guide is concentric with the valve seat.
When two diameters share a common center they are said to be concentric. Deviations from theoretical or perfect concentricity are called eccentricity.
Dimensional relationship of 2 or more items sharing a common center line.
In a wire or cable, the measurement of the location of the center of the conductor with respect to the geometric center of the circular insulation.
A tube is concentric when the center line of the inside diameter is consistent with the center line of the outside diameter.
The condition in which two fastener surfaces share the same center.
The term to describe two circles or cylindrical shapes having a common center and common axis, such as the inside and outside diameters of the flighted surface and bearing surface of a screw. Deviation from concentricity is referred to as "Runout".
In a wire or cable, the measurement of the location or the centre of the conductor with respect to the geometric centre of the circular insulation.
The measurement of how well-centered the core is within the cladding. Connector: A mechanical or optical device that provides a demountable connection between two fibers or a fiber and a source or detector.
