skf toroidal roller bearing carb – productivity improvement and maintenance cost reduction through reliability and sustainability

The CARB bearing is a single row bearing with long, slightly crowned symmetrical rollers. It combines the self-aligning capability of the spherical roller bearing with the unconstrained axial displacement ability of the cylindrical roller bearing. The optimal combination of both raceway profiles provides a favorable load distribution in the bearing, as well as low frictional running. This paper emphasizes the functioning characteristics of the SKF CARB toroidal roller bearing by means of a multibody dynamics simulation. Different conditions like load direction, races relative position or angular misalignment, are taken into consideration.
