Abstract : This study investigated the effect of combined radial and moment loads on the stiffness of cylindrical roller
bearings (CRBs). First, a general four degrees of freedom CRB model was presented that was applicable for a wide range of
loading, radial clearance, and rotational speed. The model provided a fully-occupied stiffness matrix, the contact load between
rolling elements and races, and inner ring displacements. Model verification was made by comparing the estimated bearing
stiffness under pure radial load with that from a commercial program. Then, simulations were performed for the CRB under
various radial and moment loads. Analysis of bearing performance was carried out with an emphasis on the bearing stiffness
behavior under the effects of combined loading. Numerical results showed that, without moment load, the bearing stiffness
increases with the increase of radial loading. The combined radial and moment loads introduced a nonlinear stiffness
behavior. However, this nonlinearity tended to reduce with increasing moment load.
