Abstract:
A method of forming a bicycle bearing assembly, comprising the steps of:forming an elongated inner member having a first end, a second end, an outer surface extending therebetween and a longitudinal axis extending therethrough;forming a first annular groove in said outer surface of said inner member;forming a tubular outer member having a first open end, a second open end, a center section located between said first and second open end and internal and external surfaces extending between said first and second open ends of said tubular outer member and across said center section of said tubular outer member;deforming said internal surface of said tubular outer member along said center section by rolling to form an annular center surface spaced a first distance from said longitudinal axis and formed in said internal surface of said tubular outer member;deforming said internal surface of said tubular outer member adjacent said first open end by rolling to form a second annual groove spaced a second distance from said longitudinal axis and formed in said internal surface of said tubular outer member and forming a first annular bulge in said external surface of said tubular outer member by formation of said second annular groove, said second distance being not larger than said first distance; andinserting a plurality of first bearing members located between said first annular groove of said elongated inner member and said second annular groove of said tubular outer member.
