POWER TRANSMISSION CHAINS are widely used throughout the lumber industry in a broad range of conveying, transmission, and elevating applications. They are available in either offset or straight sidebar design. The majority of bushed roller chains are best suited for slow or moderate speed drive and conveyor applications since they are made to commercial standards for clearance, fits, and limits. Broaches on one end of the rivet and flats on both ends of the bushing prevent these parts from rotating in the sidebar holes.
Letter designation of material :
Zero = no roller.
