<p>An article of manufacture comprises a flanged demountable pin (36) or bushing element having a generally cylindrical shape and a main section having a main diameter and a circumferential groove (42). Assembled within the groove is a plurality of partially annular pieces (48A,48B) forming a complete inner collar (48) with an inner diameter section and an outer diameter section. The inner diameter of the inner diameter section of the inner collar is matched to the groove (42) diameter; and in some embodiments the outer diameter of the outer diameter section of the inner collar is greater than the main diameter of the main section such that the inner collar (48) protrudes from the groove (42). An outer ring has an inner diameter section and an outer diameter section and is engaged with the inner collar to form a flange on the element. Also disclosed is a method of manufacturing to order demountable pin or bushing elements.
