By using the method of plasticity, this paper studies the relations among the prestressing pressure, the initial gap between two cylinders and the range of the plastic region for the loose running fit cylinders. These relations provide the theoretical foundations for prestressing technology of the loosc running fit cylinders. In order to avoid larger deformation of the cylinder, each cylinder is required not to produce non-restricted plastic flow in the prestressing process. Then, on condition of limiting the radius tatio of each cylinder, several formulas for tests and designs are obtained.
