Abstract:
1. A rotary machine, comprising: an inner component; a first group of cylindrical rollers disposed around the inner component, each cylindrical roller having end-faces; an outer component with a first cylindrical inner surface disposed against the cylindrical rollers; a first bearing cage associated with the first group of cylindrical rollers, wherein at least a portion of the first bearing cage is disposed inside the first cylindrical inner surface, and wherein the first bearing cage and the first cylindrical inner surface are associated with one another in such a manner that contact between the first bearing cage and the first cylindrical inner surface maintains the first bearing cage substantially concentric to the first cylindrical inner surface; a first axial stop configured to limit axial movement between the outer component and one or more of the cylindrical rollers; and a second axial stop configured to limit axial movement between one or more of the cylindrical rollers and a component of the rotary machine other than the outer component and the first bearing cage.
