For proper cylinder centering, the dimensions of the inscribed circles play a crucial role in ensuring that components fit correctly and function effectively. The requirement for the inscribed circles to be no more than 0.8mm deep and no more than 1.2mm wide establishes a limit that helps maintain precision during the manufacturing and centering processes.

When the depth and width of the inscribed circles are kept within these specified limits, it enables more accurate alignment of the cylindrical components. This accuracy is vital in applications where cylinders must rotate freely without obstruction, as well as in systems that rely on precise measurements to function optimally. Lower dimensions can also help to accommodate tighter tolerances and facilitate easier adjustments during assembly or maintenance.

Moreover, having these dimensions within the prescribed range minimizes the risk of misalignment and ensures that the forces acting on the cylinders are distributed evenly. This is essential for both the performance and longevity of mechanical systems. Consequently, conforming to these specific measurements ensures effectiveness in applications that require cylinder centering, thereby validating the choice presented in the question.
