Abstract
A double row axial roller bearing assembly includes a compressible ring between the two rows. This compressible ring prevents excessive axial forces if the respective shafts impact one another after becoming axially separated. One embodiment is fully unitized such that all parts of the bearing assembly remain with one of the two shafts if the shafts become axially separated. Another embodiment is semi-unitized such that one row of rollers and the compressible ring remain with one of the shafts while the other row of rollers remains with the other shaft. In both cases, all bearing components are prevented from falling out of position such that they return to their proper axial and radial position when the shafts come back together.
