Roller Conveyor Chain Components Pins Rollers Hitachi Roller Conveyor Chain pins are made from high quality carbon or alloy steels. The parts are heat treated to provide excellent strength and wear resistance. Standard materials and heat treatments can be found in the tables on pages 12-13, however, specialty materials, heat treatments, plating or coatings are available to suit the conditions of more difficult or challenging applications. Hitachi Roller Conveyor Chain rollers are made from high quality carbon or alloy steels. These parts are heat treated to provide excellent strength and wear resistance. Standard materials and heat treatments can be found in the tables on pages 12-13, however, specialty materials, heat treatments, platings or coatings are available to suit conditions of more difficult or challenging applications. Flanged rollers (Style "U") are specified on some chain sizes and act as tracking devices for long conveyors. Rollers of chains greater than 3" pitch are carrier rollers (i.e. the roller diameter is larger than the side bar height) which allows chains to roll reducing friction and power requirements. Style "A" Standard pins are cottered although rivet type pins can be furnished upon request. The three diameter construction allows for easy assembly in the field and the double flatted ends (Style A) provide a mechanical lock to prevent pin rotation which can occur over time. Bushings Hitachi Roller Conveyor Chain bushings are made from high quality carbon or alloy steels and generally carburized for superior wear resistance. Standard materials and heat treatments can be found in the tables on pages 12-13, however, specialty materials, heat treatments, platings or coatings are available to suit the conditions of more difficult or challenging applications. Roller Conveyor Chain bushings may be full round (Style "R") or double flatted (Style "F") depending on chain size. Style "R" Style "T" Style "U" Sidebars Hitachi Roller Conveyor Chain sidebars are made from high quality carbon or alloy steels. The parts are generally not heat treated however there are exceptions. Standard materials and heat treatments (if any) can be found in the tables on pages 12-13, however, specialty materials, heat treatments, platings or coatings are available to suit the conditions of more difficult or challenging applications. Hitachi uses precision tooling for accurate pitch control and smooth holes to assure appropriate fits for all of the components. Style "F" 11
