ABSTRACT:
A rotary machine may include an inner component and a first group of cylindrical rollers disposed around the inner component. Each of the cylindrical rollers may have end-faces. The rotary machine may further include an outer component with a first cylindrical inner surface disposed against the cylindrical rollers. Additionally, the rotary machine may include a first bearing cage associated with the first group of cylindrical rollers. At least a portion of the first bearing cage may be disposed inside the first cylindrical inner surface, and the first bearing cage and the first cylindrical inner surface may be associated with one another in such a manner to maintain the first bearing cage substantially concentric to the first cylindrical inner surface. The rotary machine may also include a first axial stop configured to limit axial movement between the outer component and one or more of the cylindrical rollers. Additionally, the rotary machine may include 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.
