The pressing fit experiment was conducted, the strain of the center part of circular cylinder was measured, and the stress was calculated. As a result, the load has increased while pressing fit process. And the load of a circular cylinder with roulette has decreased greatly. At first the compression stress increases in pressing fit process and the stress decreases in pressing about the half of specimens. When the ratio of contact area increases, the compression stress increases. Stress analysis of a circular cylinder in pressing fit process by three-dimensional elasticity theory and finite element methods (FEM). In three-dimensional elasticity theory, stress solution was given using Boussinesq-Dougall displacement function. And stress was calculated by Dini transformation and Fourier transformation. In FEM, stress was calculated using MARC. The analytical results agree with experimental data.
