To reveal the effect of roller convexity and bearing speed on the radial stiffness of cylindrical roller bearing, an analytical model of cylindrical roller bearing radial stiffness considering roller convexity and bearing speed was established. The influences of factors such as roller convexity, bearing speed, radial clearance and radial load on the radial stiffness of the bearing were analyzed. The established model was compared with other literature methods to verify the correctness. The research results showed that the radial stiffness of cylindrical roller bearings decreased with the increase of roller convexity and radial clearance, and increased with the increase of bearing speed and radial load. With the increase of radial load, the influences of roller convexity, bearing speed and radial clearance on the radial stiffness of the bearing were weakened.
