In one embodiment there is provided a shaft collar having a two component structure defined by a first component having a central bore for receipt of a shaft or axle and a second component positioned partially within the first component. The second component also having a relatively harder stiffness than the first component. The second component further includes a pair of opposing ribs positioned within the first component and about the central bore and a pair of C-shaped caps separately positioned against upper and lower ends of the pair of ribs and wherein the pair of opposing ribs have a height such that the at least a portion of the pair of C-shaped caps protrude from the upper and lower faces of the first component.
