Cr4800 carrier rollers (top rollers) are vital undercarriage parts for Cat D6H bulldozers. Made of 50Mn steel, they undergo through hardening or differential quenching to achieve HRC52-58 hardness and 8-12mm hardness depth, offering excellent wear resistance. Advanced machining centers ensure dimensional accuracy and long service life. The lubrication system reduces friction/wear for smooth rotation.
