What is a Eccentricity measuring instrument?

An eccentricity measuring instrument is a device that measures the eccentricity of a rotating object, such as a roller or a motor shaft. Eccentricity is a quantity that indicates how far the center of rotation is from the rigid center, which is the center point on the shape of the rotating object. Rotating parts such as precision equipment are often designed so that the eccentricity is 0, and if the eccentricity is off, it may cause problems, so care must be taken. There are two typical methods for measuring replies: the transmission type, which measures with transmitted light, and the reflection type, which measures with reflected light.

Application of Eccentricity measuring instrument

Eccentricity measuring instruments are used for inspection and maintenance of equipment used while rotating using motors such as machine tools, robot arms, and rollers. When selecting an eccentricity measuring instrument, it is necessary to consider the measurement method, measurement accuracy, measurement range, and so on.

An example of using the eccentricity measuring instrument is shown below.
