METHOD FOR ASSEMBLING ROLLING BEARING DEVICE

摘要

In an assembling method for roller bearing assembly according to the invention, a cage (25) featuring high general-purpose versatility is used whereas a retainer ring (40) for preventing the drop-off of first-row tapered rollers (18a) is fitted in a sub-assemble member (20) at a place diametrically inwardly with respect to the first-row tapered rollers (18a). Subsequently, a hub body (16) is combined with an outer ring (13) having the first seal ring (15) and the sub-assemble member (20) mounted thereto, as pushing out the retainer ring (40) by means of a step portion defined between a smaller-diameter cylindrical surface portion (30) and a first inner raceway (28) of the hub body (16).
