Abstract
A combined load rolling bearing including a roller assembly with a first cage including a plurality of radial cylindrical rollers and a plurality of axial cylindrical rollers is provided. The radial cylindrical rollers are supported so that they can roll on a radially outer race of a first bearing ring and a radially inner race of a second bearing ring. The axial cylindrical rollers are supported so that they can roll on a first axial race of the first bearing ring and an intermediate axial ring. A needle roller assembly is supported between the intermediate axial ring and a second axial race of the second bearing ring. The needle roller assembly includes a second cage with a plurality of needle rollers and the needle roller assembly rotates at a speed differential between the radial cylindrical rollers and the axial cylindrical rollers.
