 Centre-to-centre distance

Centre-to-centre distance refers to the distance measured between the centers of two objects, typically in the context of mechanical engineering, design, or construction. This term is often used when dealing with gears, pulleys, or other similar components to ensure proper alignment and functionality. For example, in a system involving two gears, the centre-to-centre distance would be the distance from the center of one gear to the center of the other gear.
