Abstract
A pivot bearing between first and second components (10,11) each of which is formed from a metal material. The pivot bearing comprises a hollow annular boss (14) which is formed as an integral part of the first component (10) by being drawn from the base material from which the first component is formed. An opening (12) is provided in the second component (11) and the annular boss (14) is pivotally located within the opening. The free end portion (18) of the boss (14) is pressed over such that the cross-sectional area of the free end is greater than the opening (12) thereby pivotally retaining the second component (11) on the annular boss (14). A wear-resistant plastics bushing comprising a sleeve (15) and a flange (16) can be positioned within the bearing and placed under pressure by the coupling of the components to create a required level of friction within the bearing.
