A rotary roller bearing connection with a free center comprising two concentric races, one race having a circular slot open towards the other race, the other race having a circular protrusion engaging the said slot with spacing on all sides, cylindrical rollers between the outer surface of the protrusion and the corresponding slot surface to absorb radial forces, a row of rolling elements between the face of the protrusion and the corresponding slot surfaces to absorb axial forces, of which at least the bearing row transmitting the main axial load is cylindrical rollers, and sections of circular arc form whose radii correspond at least to the radius of rolling elements disposed in the retaining row being provided in the area of the retaining row facing the bearing row and absorbing the lifting, tilting movement both at the transition of the protrusion to its associated race and at transition of the track area of the corresponding slot to the slot bottom.

Rotary roller bearing connection with a free center

A method for the assembly of large diameter rolling bearings comprising two support rings concentrically arranged one in the other, the said rings being provided with circumferential grooves, two raceways wires form-lockingly arranged in seats in the grooves under preload and rolling bodies rolling therein, at least one support ring being provided with a circular cavity in the circumferential groove which cavity is dimensioned to receive a raceway wire without preload.
