Bearing for roller wheels, characterized in that it is constituted by three annular pieces of different diameters for their mutual concentric assembly, constituted by an outer ring that has a semi-circular groove in its inner periphery, in a fixing ring that is a cylindrical body, which in one of its bases on an outer edge, has a recess in a quarter of a bull and in a bushing which is a hollow cylindrical body whose diameter is slightly lower than the inner diameter of said ring and which in one of its bases forms a peripheral projection that by its rear edge it has a recess in the same quarter in the bull ring that is in the ring, so that the aforementioned ring and bushing are assembled axially to each other under pressure until they juxtapose their respective recesses that go on to compose an equal groove and opposite to that of the aforementioned outer ring, the corresponding roller balls being included between both grooves.
