This paper derives a stiffness equation for the arbitrarily crowned roller compressed between two plates. The roller is first divided into three parts: two crowned parts and one cylindrical part. The superposition method is introduced to obtain the roller stiffness. Three-dimensional finite element analyses were used to validate the accuracy of the stiffness equation, in which rollers with circular, quadratic, cubic, fourth-order power and exponential profiles were analysed. Comparisons with finite element results indicate that the accuracy of the stiffness equation derived in this paper is acceptable.
