Abstract
Rolls of roller bearings have in their axial middle portion a load-transmitting peripheral surface and on their axial end portions there are respective radially projecting and space-maintaining peripheral surfaces. Therefore, only the space-maintaining peripheral surfaces of adjacent rolls contact one another.
