Abstract: A rolling bearing, having, for example, cylindrical rollers, is provided, between an inner ring and an outer ring, with a retaining structure for retaining the rollers. The retaining structure includes an annular retainer having a number of seats for click-in insertion of the rollers, and from an end edge of which projects a radially outer flange having a sliding surface cooperating in sliding manner with a radially inner surface of the outer ring of the bearing to support the annular retainer in a radially inner position with respect to the outer ring and so prevent the annular retainer from sliding against the rollers. The seats for the rollers each have a pair of axial projections for compensating any axial clearance between the rollers and the respective seats.

Abstract: A sealing assembly comprising a rigid sleeve-shaped baffle carrying at one end a removable cover which is also rigid, for closure of the end of the baffle, which internally is also provided with a deformably sealing element provided with radial ribs operable to define a labyrinth seal; an axial lip extends from this element and sealingly cooperates with a seat of the cover, respective axial shoulder means of this latter being simultaneously pressed under pressure against respective bayonet coupling means of the baffle.

Abstract: An axial and radial sealing assembly comprising a protection ring which can be disposed annularly about a first body and frontally of a second body, and including a first part having a support function which carries a second part which has a sealing function. The main characteristic of this assembly is the fact that this second part has first radial surfaces forming an axial seal with the second body and second radial surfaces forming a radial seal with the first body.
