Abstract
First and second raceways are positioned against a needle roller and cage subassembly, having needle rollers arranged in a plane along a pitch circle and retained within a cage, such that the rollers facilitate free rotation of the second raceway relative to the first raceway when a thrust load is applied through the first and second raceways. At least one of the first and second raceways has a recessed portion such that diametrically opposite rollers are loaded when the thrust load is applied while other rollers are unloaded, thereby facilitating linear translation of the second raceway relative to the first raceway.
