Abstract
The inner ring of a high speed roller bearing is constructed in three pieces, an inner race sandwiched between side rails. The inner race being the major load carrying member is fabricated from a high strength steel and the side rail elements are constructed from a more ductile steel. All the lubrication and oil cooling passages are judiciously located in the ductile steel constructed side rails. Scoops are provided in proximity to the side rails to aid in the delivering of oil to the lubrication and oil cooling passages.
