Rolling bearing

Claim 1

A rolling bearing comprising: an inner ring and an outer ring, said inner ring having an outer conical race and outer ring having an inner conical race, one or more rows of rolling bodies disposed between the said rings so that said bodies roll between said conical races, said inner ring having an inner cylindrical surface and said outer ring having an outer cylindrical surface, each of said rolling bodies having an outer conical surface and the axes of said bodies lying on a further conical surface, wherein said bodies are dimensioned so that the ratio between the axial length of each body and the maximum diameter of each body is more than three, and wherein the ratio between the axial length of the bearing and the distance between the outer surface of the outer ring and the inner surface of the inner ring is more than two, a first cylindrical retainer surface formed circumferentially around the inner ring conical race at the end of the inner ring conical race having the smaller diameter, said first cylindrical retainer surface being open to an end of said inner ring, a second cylindrical retainer surface formed circumferentially around the outer ring conical race at the end of the outer ring conical race having the larger diameter, said second cylindrical retainer surface being open to an end of said outer ring opposite from said end of said inner ring, a first retaining ring constructed of a deformable plastic material and secured by an interference fit to said first cylindrical retainer surface and second retaining ring constructed of a deformable plastic material and secured by an interference fit to said second cylindrical retainer surface.
