    摘要： An assembled roller comprising a cylindrical bush having eight external rib surface features and an over-molded roller. The joining edge of the opposing component parts comprises, in axial end profile, a ramp section comprising a ramp surface. The ramp surfaces lie in planes that are parallel or slightly offset by 1° to 20° to the direction or angle of approach of the respective opposed component part immediately prior to engagement, so that the ramp surfaces are adapted to slidingly engage across ramp surfaces in a resistance, rather than snap, fit. This arrangement forms a catch that will hold the component part halves together during an over-molding process as long as the ends of the bush are retarded against axial displacement.
