The Hollow Cylindrical Roller Bearings (HCRBs) have some important advantages over solid cylindrical
roller bearings such as low weight, good lubrication capability and high bearing stiffness. Additionally, it’s also known
that maximum contact stress value between the roller and race is less in hollow cylindrical roller bearings compared
to solid cylindrical roller bearings. In this paper, the effect of roller's hollow size in Hollow Cylindrical Roller Bearing
under a radial load on the maximum contact stress value and contact stress distribution is studied by using finite element
method. The maximum tangential tensile stress occurring on the inner surface of the hollow roller is also investigated.
Moreover, the effect of the penetration amount, which is a critical parameter for a nonlinear contact problem such as
roller-race contact, on the contact stress is taken into consideration, as well. It’s seen from the results that tangential
tensile stress on the inner surface of the hollow roller has an effect on the value of optimum hollow size. Besides, it is
deduced from results that the penetration amount between the contacting surfaces have considerable influence on the
contact stresses and it should be taken into consideration when analyzing the roller-race contact problem by using finite
element method.
