Abstract
A double row thrust bearing assembly () includes a bottom plate () having inner and outer conical raceways (), a top plate () with a flat raceway (), and respective sets of identically formed inner and outer rollers () mounted on respective inner and outer cages (). When the bearing is fully assembled, the apices of the inner and outer rollers directed at the same point (A) on an axis (X) of the bearing. Various relationships with respect to the size and shapes of the rollers are determined in order to maximize the bearing assembly's load carrying capacity while occupying the same spatial envelope as that of a single row thrust bearing assembly (BA) which can only support a lesser load.
