The eccentricity of an eccentric copper bushing is the distance between the center of rotation and the geometric center of the bushing.

In an eccentric bushing, because its center of rotation does not coincide with the geometric center, an eccentric motion occurs when the bushing rotates. The size of the eccentricity distance determines the magnitude and characteristics of the eccentric motion.

For example, in some mechanical devices, eccentric copper bushings are used to achieve a specific motion trajectory or to transmit power. By adjusting the size of the eccentricity, the motion characteristics of the equipment can be changed to meet different work requirements.

The existence of eccentricity makes the eccentric bushing generate extra force and moment during the working process, which puts certain requirements on the structural design and operational stability of the equipment. In the design and use of eccentric copper bushings, it is necessary to fully consider the impact of eccentricity on the performance of the equipment, to ensure that the equipment can operate safely and reliably.
