Abstract
A linear recirculation path unit for a roller bearing includes a linear loading passage, a linear unloading passage, and two direction reversing passages connected to the ends of the linear passages. Instead of simply designing the reversing passages so that the slopes or tangents of the linear and reversing passages are continuous at the connecting points, the reversing passages are arranged so that not only the slopes but also the curvatures of the linear and reversing passages vary continuously throughout the recirculation path, thereby reducing centrifugal acceleration of the rolling elements in the path, with consequent reductions in impact forces on walls of the passages, sliding function, and vibration induced noises.
