Abstract:
A tool for the extraction of a bearing from a wheel, including a bearing from an in-line skate wheel, the wheel including a concentric cage, adapted to house at least one bearing having an outer frontal face, the bearing having an outer ring, and an inner ring, the inner ring having a determinate first diameter, the inner ring and the outer ring being spaced from one another via bearing members, said tool comprising:a manual gripping member having an end;an end piece extending from said end of said gripping member, said end piece having a truncated conical portion, said truncated conical portion having a relatively large base positioned towards said end of said gripping member and a relatively small based spaced remotely from said end of said gripping member, said large base having a determinate second diameter, said end piece further having a coaxial annular collar that is extended radially from said small base, said annular collar having a determinate third diameter, said large base second diameter and said annular collar third diameter each being at least slightly less than said inner ring first diameter;said end of said gripping member comprising at least one abutment surface forming a shoulder extending radially beyond said inner ring first diameter, said end of said gripping member thereby having a structural configuration adapted to take support against the outer frontal face of the bearing, said abutment surface of said end of said gripping member, during said support, being spaced from said annular collar by a distance corresponding to a positioning of said annular collar beyond a rear surface of the inner ring of the bearing, whereby the inner ring is gripped by exerting a tipping motion on said gripping member and, thereby on said end piece.
